One Direction heartthrob Louis Tomlinson has admitted that he was once suspended from school after misbehaving while acting in a student-led production of 'Grease'.

Now magazine reports that during an interview with a U.S. radio station, Tomlinson explained that he pulled down his trousers on stage and was subsequently punished for flashing his bare bottom at the shocked audience:

"I once got suspended for a week for getting my bum out during a school performance of 'Grease'."

Meanwhile, Tomlinson took to his official Twitter page this afternoon (October 19) and joked that his girlfriend confused Bond star Daniel Craig with 'Seven Days' singer Craig David: "So @EleanorJCalder just enlightened me to a great James Bond film staring Craig David..."
