And you thought the tension between Jeff Conaway and his girlfriend was awkward to watch…

For Season 3 of Celebrity Rehab, Dr. Drew Pinsky and producers have upped the dramatic ante. Actor Tom Sizemore has just been included in the final lineup for the VH1 reality series. This means he will be seeking treatment at the same time as Heidi Fleiss.

Despite an impressive body of work, Sizemore’s personal life has been checkered with a host of legal issues. In addition to numerous troubles with drugs, the Saving Private Ryan star was also convicted in 2003 of assaulting and harassing his then-girlfriend. That woman was Fleiss, the former Hollywood madam. According to TMZ, Tom checked himself into The Pasadena Recovery Center last Friday, one day after being arrested for an outstanding warrant.

Fleiss, along with Mackenzie Phillips, Dennis Rodman, Joey Kovar (Real World: Hollywood) and Lisa D’Amato (Top Model), had already been announced for Season 3. Sizemore, country singer Mindy McCready, Alice in Chains’ Mike Starr and Playboy Playmate Kari Ann Peniche now round out the final cast.

Eight episodes of Celebrity Rehab with Dr. Drew are scheduled to premiere sometime early next year.
