Joe Jonas is inspired by Sir Mick Jagger

Joe Jonas is inspired by Sir Mick Jagger.

The 19-year-old Jonas Brothers frontman - who wears a purity ring as a sign of his pre-marriage chastity - says the womanising Rolling Stones singer is his musical hero and he tries to act like him on stage.

Joe said: "I would love to meet Mick Jagger. A lot of what I do on stage is inspired by Jagger. I love the way he performs and how he dances."

Even though Joe has a purity ring, the teen star admits he has crushes on several famous women.

The musician - whose brothers Kevin and Nick also abstain from sex - added: "I love Leona Lewis. I've been watching her video, she's gorgeous. I also like Natalie Portman, Emma Watson and Cheryl Cole. I like a lot of people."

Joe also revealed he hopes any future girlfriends understand that his work has to come first.

He explained: "I need to be with someone who understands I won't be around a lot. It's also important for me to have someone that makes me happy when we talk on the phone. I want to be happy."
