Eddie Kaye Thomas -- Alleged Knife-Wielding Tryst Chick Has Trespass History

"American Pie" star Eddie Kaye Thomas sure knows how to pick 'em ... the woman who allegedly barricaded herself inside his home with a knife after a one-night stand has a history of SERIOUSLY wearing out her welcome.

TMZ has learned ... 31-year-old Roxanna Bear was arrested twice in February ... once for public intoxication and once for trespassing.

Police say Roxanna was loitering around the Regent Beverly Wilshire hotel -- where she was NOT a guest -- on Feb. 24. She refused to leave when hotel security confronted her ... so they called the cops.

The other arrest came just a few days before, when police say Roxanna was stumbling drunk in the middle of Wilshire Blvd. She was allegedly combative during both arrests -- though no knives were involved.

Also, we've learned the L.A. County DA just hit Roxie with 5 charges for the incident at Eddie's house ... including vandalism, exhibiting a deadly weapon and resisting arrest.

As TMZ first reported, EKT picked her up the night before at Mel's Diner ... cops had to use tear gas to get her out.
