The pop superstar has always dreamed of perfecting ballet and figured she'd be a natural because she has been dancing all her life.

She says: "I'd like to learn how to do pointe, ballet dance. I went to have lessons?and I'm thinking, 'I dance, I'll be able to hang.'

"So I didn't tell anybody it was me, I went and got on my tights, I walked in and I was completely embarrassed. I was horrible, terrible?I'm too old?You have to start when you're, like, five years old."

And, after hitting 25 on Monday, Knowles now has a list of things she wants to try before she turns 30.

She adds: "I wanna learn Arabic. It's very hard, I tried. And I wanna learn how to cook... and I wanna learn how to skydive."
