Rachel Uchitel, the first woman linked to Tiger Woods following the public expose of his extramarital affairs, has threatened to file a lawsuit against a Las Vegas showman for making derogatory remarks about her on Facebook.

Comic and showman Jeff Beacher apparently referred to the socialite as a "hooker," "slut", and "whore" on his Facebook page, according to a letter obtained by TMZ.com.

A legal team for Uchitel was said to have shot off a letter claiming the comments amounted to defamation, the New York Post reported.

They have demanded the remarks be removed from the popular social networking website. (ANI)
