(Cover) - EN Showbiz - Jennifer Aniston's dentist plays the guitar while he is treating her.

The actress explained the medical professional entertains her with his music while she is lying in the chair.

And the former Friends star couldn't even stop him if she wanted to, because her dental expert does it when she can't speak due to the treatment.

"My dentist plays the guitar for me when I have the moulds in my mouth. He literally I mean it's hard but it's the truth," she told talk show host David Letterman.

The TV interviewer seemed in disbelief and asked Jennifer why on earth her dentist would do such a thing.

Appreciating the weirdness of the professional's behaviour, the Just Go With It star jokingly dismissed it as typical Los Angeles craziness.

Jennifer, who is currently promoting her new movie Horrible Bosses, proved her comic talent when she deadpanned with perfect timing.

"Don't ask, it's Hollywood," she quipped. (C) Cover Media
