AceShowbiz - A publicist for actor Tom Sizemore has cleared up reports suggesting the actor's girlfriend has gone missing, insisting the woman at the center of the disappearance case is just "a friend" and the star is "not a suspect".

Actress Megan Wren, 25, is reported to have gone missing on March 31. She was last seen in Los Angeles and was said to have been living with Sizemore for six months prior to her disappearance. However, the "Black Hawk Down" star's representative Charles Lago has played down the pair's relationship, claiming Wren is simply an associate of the actor's.

And he is adamant Sizemore, who has been helping cops with their investigation, is not being treated as a suspect. Lago tells E! News, "The girl is not his girlfriend, never was his girlfriend; it's a girl he knows. It's a friend of his... She's just a girl he knew through someone else."

"The day she went missing on the 31st, Tom was on a movie set four days prior to that and a week after that, and police confirmed that. And he stayed in a hotel and he wasn't even home. Tom is not a suspect at all. Tom did speak to the police, he offered for them to come search his apartment and they declined saying it wasn't necessary."
