All she needs is a stripper pole!

Jennifer Aniston plays a "nympho" dentist in the new flick Horrible Bosses, currently shooting in L.A. -- and, naturally, the 41-year-old's character can't keep her clothes on!

In one scene that shot August 10, a set source says in the new Us Weekly, Aniston did a "striptease" for a male costar. Still, the insider says, Aniston "doesn't think she's pretty."

Get more details on Aniston's peekaboo shoot in this week's Hot Stuff video, as revealed by Senior Editor Ian Drew, plus special guest, hip-hop superstar T.I.!
