'Black Hawk Down' actor Tom Sizemore is being sued by an ex-girlfriend for allegedly not paying child support for the couple's twin boys, TMZ is reporting.

In the lawsuit, filed last week in L.A. Superior Court, Jinele McIntire claims the troubled actor owes her $58,800 in child support and hasn't seen the 4-year-olds since taping VH1's 'Sober House' earlier this year.

The first line of the suit pretty much sums up McIntire's point of view: "TOM SIZEMORE is a DEAD BEAT DAD."
