Kim Kardashian has spoken about her friendship with Justin Bieber today, amidst claims their relationship is unsuitable.

The pair have been attacked by Right-Wing nutjob Bill O'Reilly in the States for doing things like their recent beach photo shoot.

Justin and Kim are regular Tweet buddys but Kim, 29, claims that the pair are 'Just having fun' saying: "The shoot was fun, we had a good time. Everyone is entitled to their own opinion on it, but we were just having a good time... Everyone has loved it... It was all in fun."

Speaking on US chat show Lopez Tonight, Kim went on to say that she would date Justin if he were just a little bit older.

She said, "He has this swag to him, you just have to meet him... he definitely has this swag to him."
