Justin Bieber has revealed he wants a girlfriend with "kissable lips".The 19-year-old singer split from his girlfriend of almost two years, Selena Gomez, a few months ago and is on the lookout for a new love but he has some strong ideas on what she should be like.He told Teen Vogue: "I need a girl [who is] funny, who can make me laugh, who's, you know, beautiful on the inside and out. Someone who's intelligent, who can keep a good conversation- who has kissable lips."Despite his worldwide fame and success, Justin previously revealed he has trouble trusting people and only has four real friends.He said: "I get good vibes from people all the time, and I probably could get along with them and be their friend, but now I just don't trust anybody. Literally, my phone never rings. I only have, like, four people that I keep in contact with."I don't need a bunch of friends to make me happy. I just need the people close to me that I love, that's all."
