Lady Gaga's album Born This Way has come straight in at number one. The singer's known for her outrageous outfits so we thought we'd look back at a few.
This dress - made out of meat - caused a bit of a stir (not a stir fry though). She wore it when she won eight awards at the 2010 MTV Video Music Awards.
Check out this dog collar and funky make-up as Lady Gaga - real name Stefani Germanotta - goes to do some filming in New York.
Remember this bizarre look? This is what she wore for the Brit Awards 2010. We think she looks a bit like a Barbie doll here.
Back in 2009 Lady Gaga performed at Glastonbury wearing this sparkly suit, complete with its own triangle.
How does she get her hair like that? Maybe she's had tips from Jedward. Here she took over editing a London newspaper for the day. Wonder if she found it hair-raising?
Wow, it's Lady Gaga in red. She certainly knows how to keep her audiences guessing what her next costume will be like.
It's another cool combo of trendy clothes and marvellous make-up. Wonder if this will catch on this summer?
