It looks as though the cat might be out of the bag as LeAnn Rimes supposedly knows that her husband Eddie Cibrian is cheating on her, but isn't doing anything about it. A source revealed to Star Magazine on Thursday that Cibrian is addicted to cheating on his wife and is even jealous of her success, too.

While Rimes is supposedly embarrassed over her husband's extra marital affair, the source says that she's doing nothing about it as she doesn't want to harm her public image right now.

Cibrian has allegedly been seen with his mistresses at restaurants in the San Fernando Valley, California area and at the Equonix gym in West Hollywood. According to the insider, his indiscretions aren't bothering Rimes at all.

The source said, "LeAnn performed at Wendy Williams' 50th birthday party in July, and Eddie was all over girls right in front of his wife. LeAnn didn't do anything about it. She just goes on with her life."

As far as Cibrian though, the source added, "He has an addition; he has a 'look at me' issue. A lot of people want to get caught because they are addicted to attention. Eddie has no money, he doesn't even work and is very jealous of his wife's success."

Just recently, Rimes poked fun at tabloid magazines that make up stories about her personal life and marriage to Cibrian.

According to E! Online, Rimes wrote on her Twitter account on Thursday, "If you combine OK! Magazine and The National Enquirer's stories that they're 'investigating' this week you get...Eddie doesn't want to have kids with me so he's been cheating on me since April & we're headed for that 50 million dollar divorce we were gonna go through almost a year ago," Rimes told her fans. "I'm sure there's aliens involved in it too, but we only get told bits and pieces."

She added the hashtags: "#nextweekstabloids #there'syourquoteforyourdeadline #bothownedbythesamecompany #synergy #alwaysintheknow #thatwasfun."
