Britney Spears and Take That are both releasing albums on Monday, and both acts are bringing out TWO versions.
Britney's deluxe version of her album - called Circus - has an added DVD, while Take That's - called The Circus - has a book that goes with it.
But they aren't the only stars releasing two versions of the same album at the moment.
Rihanna and Leona Lewis are both bringing out new versions of the albums they released last year, with extra tracks and content.
So what do you think of deluxe albums? Are they a good deal for fans, because they get even more from their fave artists, or are they a rip-off?

"Deluxe albums rock! McFly released one in September with a two-hour DVD and a CD with four new songs and a 32 page booklet. Best present I ever got!"
Rachel, 13, Belfast, Northern Ireland
"I think it's silly that pop stars make two albums. It's too confusing. They should release one at a time."
Maria, 13, Cheshire, England
"If the two are released at the same time then I think it's OK. It's just giving consumers a choice as to whether they want to pay a bit more for a DVD or a few extra tracks. If they're released after then it's a con to attempt to get more album sales, I think, by convincing people to buy the same album AGAIN just to get the DVD."
Sarah, 12, Stoke, England
"Deluxe albums are half and half. They are good because you have new tracks on them and you can get something with them, but the bad sides are that if you have bought their last album, which has all the songs on it, only a few get added. I don't think they're that great."
Ara, 10, Edinburgh, Scotland
"I think it's okay if it just comes with a book or something, but if it just has a couple of extra tracks it's a rip off, especially if you already have got the original album."
Harriet, 13, Isle of Wight, England
"Well, if they release the deluxe album AND the normal one at the same time then it would be better, but some artists release the normal one first and then bring out a deluxe one a month later with two more tracks on??? STUPID!"
Hannah, 12, Aberdeen, Scotland
"I think deluxe albums are better because they have their newest songs on."
Louise, 12, Newcastle, England
"I think deluxe albums are a waste of time as people can sell the extra feature separately."
Lily, 10, Berkshire, England
"I think they are okay, if there are at least three different exclusive features. If there are just new singles, you might as well buy the single and save your money."
Lizzie, 12, England
"Well, I think it's rather stupid, especially when a normal album comes out and then a deluxe one comes out - it's just plain stupid. Though you do get more songs on a deluxe album."
Roxanne, 13, London, England
"I think if you really want to follow the artist(s) you should buy the deluxe album but for good, entertaining, cheap music I would just buy the first album."
Calum, 12, Scotland
"I think it's a reasonable idea because if you were a fan of Leona and she released a couple of new songs that you loved or it had an extra DVD then it would be great. If you don't like the majority of songs then it's pointless."
Lucy, 9, London, England
"It's worth it - you get more great songs and behind-the-scenes and get to know the band even better!"
Fifi, 15, London, England
"The artists are stupid doing this. Rihanna had two number one hits (Disturbia and Take A Bow) and released them on a deluxe edition when she could have used them for an upcoming album and already have two number one hits on it, ensuring the album is a success."
Ryan, 14, Birmingham, England
"I don't have anything against deluxe albums. I think they give fans more entertainment with the DVD and the other features."
Milly, 13, England
"I like Take That but I would not buy a new CD because it is just a waste of money."
Tom, 11, Preston, England
"They're not very good at all; they're a rip-off!"
Alex, 9, Shropshire, England
"I think deluxe albums are good! They have new songs that most people haven't heard. I got the McFly deluxe album and I love watching the DVD. Most people like to know what they do behind the scenes and the booklets tell you a lot about them."
Soph, 14, Surrey, England
"I think it is a waste of time and money."
Sophie, 12, Gloucester, England
"I think if you're going to bring out a new deluxe album you might as well make a new album because people who bought the original might want the deluxe but they are paying £12 or £13 for a few extra songs and it is pointless."
Courtney, 11, Bristol, England
"I think it is a good thing because you get to hear more of the artist's songs and you never know, it might be a number one!"
Dominic, 9, London, England
"I think that deluxe albums are just albums that have more songs on but cost more. They are cons. They should just have the tracks on in the first place!"
Olivia, 10, Wigan, England
"I think pop stars shouldn't have a deluxe album because my brother's got Rihanna's 'Good Girl Gone Bad' album and he wants the song 'Take a Bow' but that's on the re-released version of the album he's already got. So what's the point of getting the album all again?!"
Amelia, 13, Buckinghamshire, England
"I really like Take That so I think a deluxe version is fantastic for me. I am getting Take That's for Christmas and I am going to do all the songs in my band!"
Tomos, 12, Cardiff, Wales
"It's really unfair! I spent my money on Rihanna's album 'Good Girl Gone Bad' last year. And I went to a music store to find she'd released another one but with more of her well known songs on! It's really stupid and a way for the artist to make more money!"
Emma, 13, London, England
"It's just a waste of money if there're only three or four new songs on it."
Charlotte, 13, Leicester, England
"I think that if it's a really good album with a lot of extra songs on it, then it's good value, especially if they are your fave artists. However, if it's just a few songs, it's a bit of a rip-off. Also, it's a bit confusing knowing which one is which, so you could end up buying the normal version instead of the deluxe version or the other way around."
Lucy, 11, Devon, England
"I don't see the point in singers releasing deluxe albums. It's just a con to make you buy their album."
Marie, 11, Blackpool, England
"I think that deluxe albums are a great idea, as long as you release them at the same time as the normal album, like with Beyonce's album. I was really annoyed when I bought Leona's album and then the deluxe version came out with two great new singles."
Meg, 12, Suffolk, England
"I love Duffy and I've got all of her CDs, and now they're re-doing a deluxe I'm a bit angry, but I'm hoping to have it for Christmas!"
Ele, 10, Wales
"I think it's annoying when you buy the normal album and then a few months later, the artist releases a deluxe album with more songs on it and you don't have them. I was annoyed when Rihanna did this."
Hattie, 11, Warwickshire, England
"One of my friends got the new deluxe Leona Lewis album today and it had about three extra tracks and a DVD. In my opinion, that's good value. But if the deluxe album is just a couple of B-sides, then that's ridiculous."
Alex, 12, Leicestershire, England
"It's a business thing. In business it's all about advantages and the deluxe albums are a form of advantage."
Fay, 13, West Yorkshire, England
"I think it's well bad, if an album is released and then later a deluxe album is released that's just the same but with a few new tracks. But if a deluxe album is released at the same time and a person can choose, I don't see any problem."
Alan, 13, London, England
"It's just a waste of money if there are only three or four new songs on it."
Charlotte, 13, Leicestershire, England
"It's all just a money-making scheme. I don't think it's ridiculous because this is their job. If they want to earn money in cheating people, yes, of course it's not nice, but not illegal, so leave them alone."
Kulsuma, 11, Birmingham, England
"I think they should just make deluxe albums for well known singers, because they have more to offer. I would only buy a deluxe album if I really liked the singer."
Alexa, 10, Herefordshire, England
"I think it's pointless really. Why have a deluxe version with the same name!?"
Zainab, 12, London, England
"I think it's great if you use a legal website where you can download the new tracks if you already have the standard album, and if you've just got around to buying that album it's a good bonus - but I don't see the point in books and DVDs with the albums."
Rowan, 12, Somerset, England
"No. I think it's a bit of a rip off as you're paying for the album all over again. I think they should just bring out a single with the songs on, then you're paying for what you deserve."
Mariann, 13, Glasgow, Scotland
"I think that if you really like the artist, then it's good value. However, if you only like one or two of the songs, it's a waste of money."
AJ, 13, Devon, England
"I love music and Britney Spears, I'm so buying that album!"
Sophie, 10, London, England
"I think it's just great for fans but it's also good for the people making the albums."
Mai, 12, Oxford, England
"I don't see the point. The fact that Take That and Britney are having DVDs and books are bribery. Deluxe albums are pointless because people wouldn't get two CDs almost the same just because of 3 or 4 new songs!"
Adam, 12, Birmingham, England
"It's a waste of money if you only have several exclusive tracks."
