Loads of celebs turned out for one of the most important nights of the year in the music industry - the Brit Awards.
It was a great night for Duffy, who won THREE of the four awards she was nominated for.
But the Welsh singer missed out on best single to Girls Aloud - who won their first ever Brit.
Newsround's Ricky was there to meet the stars and soak up the atmosphere...
Working for Newsround can be really great.

Sometimes you get a glimpse into what it must be like to be a major celebrity.
I got to stand on the red carpet at the 2009 Brit Awards to speak to some of the singers and bands hoping to pick up an award.
All the famous names like Duffy, Estelle, The Ting Tings and even Alexandra Burke were surrounded by lots of important people ushering them along to be interviewed by the likes of me.
They were out in force to celebrate the success they've had in the charts over the past 12 months.
Ricky meets the stars at the Brits
X Factor winner Alexandra told me how excited she was about attending the Brits.
She said that this time last year she was at home watching the show in her pyjamas.
She told me she had no idea that she would one day be taking part.
I managed to catch up with Strictly Come Dancing winner and now chart topper Alesha Dixon.
She told me that she's a big supporter of other British female solo acts like Duffy and Adele.

I also found out that when Alesha was younger she went to the same college as me, which is pretty cool!
It's not all about the celebrities though, the Brits play a very important part in the music industry.
They celebrate new and established acts from Britain and across the world.
Many of the singers who win an award go on to sell millions of albums, and it boosts their digital download sales.
It turned out to be a great night for Duffy, she won three awards!
I had a great night meeting all the singers, including Duffy.
Just before the ceremony kicked off I asked her if she had a good luck charm.
She didn't, and instead wanted me to give her one, so she took my very own ear piece that I use when I'm live on Newsround!
Luckily, after a while, I got it back!
