from www.tmz.com – TMZ has learned Carrie Prejean just pulled out of a talk she was supposed to give this afternoon at the Capitol Hill Club in Washington D.C. — an exclusive club for Republicans only.

An insider at the Capitol Hill Club tells TMZ Carrie canceled five minutes before she was supposed to speak because her camp wanted to avoid a repeat of last night’s “Larry King Live” fiasco — when she almost walked off the set.

Carrie faced a fresh wave of criticism this morning after her former hookup told us she wanted him to lie about her sex tape and tell people she was underage when she filmed it … when she was really 20-years-old.
