Rebecca Gayheart and Eric Dane's marriage in trouble?

Rebecca Gayheart and Eric Dane's marriage is in trouble reports Life&Style. An insider close to the couple tells Life & Style exclusively, "She's having problems with his addictions. He went to rehab to try to get it all straight before the birth of their second kid. They are trying, but the marriage is not working out."

Life & Style has learned it's so serious, Eric has voluntarily remained in rehab weeks after completing a 30-day treatment program to beat his dependence on prescription painkillers. A source confirms that Eric is improving, however, he and Rebecca "aren't talking much." Reveals the insider, "Rebecca is trying to hold it all together as she deals with her pregnancy, but she thinks right now it's better if she's alone."

The source adds that Eric wants to make sure his problems are behind him before moving back into the house, so for now, "Rebecca's family has flown in from Kentucky to support her."

Rebecca was seen without her wedding ring on Aug. 18 at a book-launch party in LA and again not wearing her ring on Aug. 27 leaving an LA Target.
