Selena Gomez says Justin Bieber has stopped her from ''playing games''.

The 19-year-old star - who has been dating the 'Baby' hitmaker since December 2010 - admitted while she used to toy with people's emotions in the past, she has come to realise that such behaviour is ''silly''.

She said: ''I've played games in the past, but now I've finally met someone who makes me not play games. If you're playing games, you need to ask yourself if that person is really for you. Games are silly.''

The 'Wizards of Waverley Place' actress now thinks the best relationships are based on ''compassion and honesty'', and believes being yourself is the key to success.

Selena explained to TOTP magazine: ''I've conformed to a lot of guys that I liked before; it's very easy to want to be what they want you to be. But in the end, it just wasn't enjoyable - I was miserable half the time. The best person you can be with is someone you can be yourself with.''

Despite their fame, Selena recently insisted she and Justin have a very normal relationship.

She said: ''I'm just like every 19-year-old girl. If you're in love, you're in love to the fullest, and you just want to go to the movies, hang out, and be as normal as possible.

''I'm fortunate that I've found someone who has that philosophy.''
