Los Angeles, March 11 (Reuters): American Pie actor Tara Reid is suing to block an ad urging her to ?let it all hang out?, calling it a taunting reference to a red-carpet arrival in which she accidentally bared her breast.

Reid filed a suit against Sky Las Vegas Condominiums Inc. on Wednesday to stop the ad in Vegas magazine, which she said had ?caused her humiliation, embarrassment, hurt feelings, mental anguish and suffering?.

The advertisement, which appeared last month, said ?Dear Tara Reid, Come Let It All Hang Out?.

Reid, 29, was posing for photographers at a birthday party for rap entrepreneur Sean P. Diddy Combs in November, when the strap of her gown slipped off, exposing her breast.

Reid accused the developer of taunting her ?in a sexual manner? and ?putting her in a false light in the public eye?.
