London, Mar 25 : Music mogul Simon Cowell had turned down US President Barack Obama's dinner invite - because he "wasn't available".

In an interview to US chat show host Jay Leno, the X-Factor judge revealed that he rejected a dinner invite Obama because he was too busy.

"He wanted to have dinner and our diaries didn't quite match," the Sun quoted him as saying.

"We just didn't quite connect," he added.

To which shocked Leno asked, "And what were you doing - whitening your teeth? Fixing your hair?" (ANI)
