Not cool, Tom Sizemore.

The Saving Private Ryan actor has been charged with one count of misdemeanor spousal battery stemming from a violent August 5 altercation in which he allegedly whomped on his girlfriend - not his spouse, interestingly enough.

Tom Sizemore, 47, was originally due to be arraigned today in Los Angeles Criminal Court, but the hearing was pushed back to Wednesday, October 7.

Following the bust, the Golden Globe-nominated head case spent a brief stint in Los Angeles County lockup. He was released after posting $20,000 bail.

Few are shocked when Tom Sizemore and trouble find each other.

Tom Sizemore is still scheduled to take part in the next season of VH1's Sober House, which has put him under the same roof as other troubled celebrities.

Including his ex-girlfriend, former madam Heidi Fleiss (above).

Wonder if that's going to be super awkward. That show should recruit Kari Ann Peniche while they're at it. Nothing like nude tapes coming out of rehab.
