RihannaShe may be flying high now.

But Rihanna's revealed she's had her fair share of downs in the past.

Especially as far as her lovelife is concerned.

Chatting to MSN, she said: "I've been cheated on. When I was young my boyfriend was unfaithful, it happens.

"What did I do? I walked away.

"If someone does it once he's going to do it again. I wasn't in a marriage, you know, so as soon as something like that happens you have to walk away."

Good on you, Ri.

She also adressed the issue of her private life since becoming, like, hugely famous, saying: "I don't have a private life.

"It's been hard to adjust to it all. It's been hard, definitely. But it's something you just have to deal with."

And, you'll never guess who she may join forces with next - although only musically of course. Why, it would be Mr Mark Ronson.

She confirmed: "I love Mark Ronson. We've talked about doing some thing together on my next album."
