Justin Bieber has claimed he could win a fight with all three of the Jonas Brothers. The 16-year old, who is said to be feuding with the trio insisted that he would definitely beat Kevin, Nick and Joe if they ever came to to blows. Bieber told Top of the Pops magazine: “Oh, I could take all three Jonas Brothers…I’m a beast!" The Never Let You Go singer added: “Supposedly there’s a war between my fans and Jonas Brothers fans, but basically we’re all friends. I love you all, but why do you guys have to fight?” Justin, who appeared at 95.8 Capital FM's Summertime Ball with his mentor Usher over the weekend also confessed that he loves being famous…because he doesn't have to go to school. Bieber said: “School sucks! I want my world to be fun. No rules, no parents, no nothing. Like, no one can stop me!”
