The birthday boy's festivities were held at London's Cirque du Soir club. According to E! News, star guests included British singer Ella-Paige Roberts Clark and actor/rapper Jaden Smith.

A source told E! that all were asked to leave after an argument ensued between Bieber's entourage and the club's security. It was then that Bieber went straight back to his hotel.

While the cause of the argument is not known, Bieber's friend Ryan Butler tweeted, "This is unbelievable. Can't even have fun on his birthday."
