LeAnn Rimes is about to learn a very tough lesson about love: What goes around comes around. Soon after the scandal broke that both Eddie Cibrian, 36, and the blond country star, 27, began a covert passionate affair on the set of Northern Lights, a Lifetime TV movie that aired in March, 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.”

“He has a friend drop him off at Scheana’s apartment, where he’ll usually spend about two hours,” the insider reveals. “Then a friend picks him up. He never spends the night at Scheana’s because he’s afraid LeAnn will catch on. But he’s made it clear to Scheana that he wants to continue seeing her.”
