EXCLUSIVE: Linda Fiorentino's Ex To Be Sentenced

Former film seductress Linda Fiorentino's ex-boyfriend, disgraced FBI agent Mark Rossini, is to be sentenced in Washington, D.C. federal court on Thursday, RadarOnline.com has exclusively learned. In December, the good-looking, former high-profile agent resigned from the FBI, and pled guilty to five counts of illegally accessing confidential FBI information for a person described as Madame X. That person was his then girlfriend Linda Fiorentino, who had risen to fame on the high heels of her role in The Last Seduction. (She's now telling friends she's single again.)

Friends of the actress claim that she hooked up with Rossini after meeting him one night at Elaine's restaurant in Manhattan. Fiorentino, who had an unexplained fixation with now convicted Hollywood private investigator, Anthony Pellicano, provided information to the P.I.'s legal defense team that Rossini had illegally downloaded from FBI computers. Rossini was charged with hacking into the secret case files 40 times. Fiorentino and Rossini tell friends that all their troubles began with Radar!

On July 9, 2007, we wrote about Rossini's fixation with the star and how he was helping get her information on the Pellicano case. In Rossini's plea agreement the feds mention that story and also the fact that when Rossini was officially questioned about the story in February 2008, he flatly told investigators that our story was false. Naughty! Naughty agent Rossini! He now faces a maximum sentence of five years.

Rossini should have asked someone from the crew of Men In Black for their thoughts about Fiorentino before hooking up with her. Sources say that many actors and crew agreed Fiorentino was so difficult to deal with they never wanted to work with her again. Not surprisingly she wasn't in the Men in Black sequel.
