Justin Bieber, who turned 17 last week, spoke to People magazine about his physical attraction to "Wizards of Waverly Place" star Selena Gomez and how he got flirting advice from 'Twilight's Robert Pattinson.

Bieber and Gomez came out as a couple at the 2011 Vanity Fair Oscar Party. Speaking about his new girlfriend he said "She's hot… Of course every guy likes the girl to be hot, which Selena is…She is a really great person and I think she has the best smile in the world."

He also said "It's so important that a girl makes me laugh. But I like to mess around and pull jokes on people so I like to be around people who make me laugh and share my sense of humor. That's Selena for sure."

It seems that Pattinson has been giving Bieber flirting tips too. He said "One day Robert Pattinson came up to me at a party and said, 'For whatever reason, people love our hair and it's always a great ice-breaker with girls.' He is like, 'Hey my name's Robert. Want to touch my hair?' I thought he was joking, but it really works."

And Robert Pattinson is right people really are obsessed with Bieber's hair. Last month Bieber cut his chestnut locks and he lost 80,000 Twitter fans! The 17-year-old singer and actor didn't see phased by his loss of fans. He posted "im not shaving for a month so you all can see my mustache.. im pumped (sic)."

A mustache, a new look and Robert Pattinson to give you dating advice…how could it go wrong!
