LeAnn Rimes is about to learn a very tough lesson about love: What goes around comes around. As the world knows, the blond country star, 27, fell for actor Eddie Cibrian, 36, on the set of Northern Lights, a Lifetime TV movie that aired in March. Though both Eddie and LeAnn were married at the time, they began a covert passionate affair. Their secret came out, however, right before Northern Lights premiered, when photos surfaced of the duo sneaking in and out of a beachside Malibu hotel.

Soon after the scandal broke -- and both Eddie and LeAnn had filed for
divorce from their spouses -- Life & Style revealed a bombshell. Not only had Eddie been cheating on his wife with LeAnn, he'd also been carrying on a three-year romance with 24-year-old aspiring actress Scheana Marie Jancan.

Since then, Eddie's slyly been playing the role of faithful boyfriend to rich and famous LeAnn. But Life & Style can once again expose him for the serial cheater he is. "Eddie has recently started seeing Scheana again," an insider tells Life & Style exclusively, noting that they were together on Oct. 21 around 1 a.m. "He told her he's only with LeAnn for the publicity and that he plans to end things with her soon."
