Britney Spears turns the big 3-0 in less than two weeks, and she's revealing to UK's Stylist magazine that Gwen Stefani is her "dream musical collaboration." We can just imagine how hot that would sound!

The 29-year-old mama of two, who is currently on her Femme Fatale UK tour, has also just launched her latest perfume, Cosmic Radiance.

Brit has been criticized over the years about her fluctuating weight, and she admits to the mag that her biggest daily challenge is “trying to get up and go work out in the morning. I haven’t worked out in, like, two weeks. Sometimes it’s hard to be motivated. But once you get up and do it you feel like you’ve conquered the world.”

The "Criminal" singer, who has been dating agent Jason Trawick since 2009, also talks about her love of chocolate and comments on former Mickey Mouse Club buddy Ryan Gosling's career.

    "Oh, I’m a huge fan; I think he’s amazing. I think he’s a wonderful little actor. He definitely has that ‘something’ on film; on camera, which is really cool. So I’m very happy for him.


Her bucket list wish? Brit says "to go skydiving." You go, girl!
