The former Friends star boasted of giving trims to family and friends while she was at school, and she proved her prowess by giving Kimmel a re-style during the launch of Jimmy Kimmel Live's new time slot on Tuesday (08Jan13).
Before tackling Kimmel's hair, Aniston revealed she used to help out her actor father, John Aniston, by giving him regular trims.
She says, ""I'm really nervous, I'm kind of shaking... It's been 30 years since my last haircut, so lets go for it. (The last person whose hair I cut was) my dad and he was on a soap opera at the time so that should give you some confidence.""
The actress made a dramatic entrance on the show by walking on sporting safety goggles and gloves, and carrying a sledgehammer, which she used to destroy Kimmel's desk as part of a comedy skit.
