It's in stores right now!
It's that time of year again... and the Comic Relief recruits for 2009 are five bright, young, colour co-ordinated things!
That's right - the ladies from The Saturdays have made their mark on an 80s feel-good classic, 'Just Can't Get Enough'.
And just because you might have seen mum or dad dancing to the original, doesn't mean this cover version isn't equally as cool!
The keyboard synthesisers and electronic drum beats are all still there - but this time with some VERY sassy vocals to sing along to.
And who doesn't mind singing for such a good cause?!
Even though most of The Saturdays weren't born when this song first came out, the girls have taken the lyrics and made them their own.
Clearly they're crazy about someone: "We walk together, we're walking down the street. Every time I think of you I know we have to meet!"
And it's someone they know will brighten up their day too: "And when it rains, you're shining down for me (I just can't get enough, I just can't get enough)."
Maybe it's their true love? Or maybe it's a new love?
Will you still be humming it next week?
We've been humming it around the Newsround office, so you probably are as well!
The catchy tune is getting lots of airplay already - it's even made it onto BBC Radio 1's A-List.
Hear it once and you'll be chanting "I just can't get enough" for the rest of your day.
Will it make the charts?
All eyes will be on the Top 40 next week to see if you just can't get enough of... well... 'Just Can't Get Enough'!
The Saturdays will have some tough competition in the UK charts - but, with such a fun track being in aid of such a good cause, we'd be very surprised if it didn't go all the way to number one.
