Did Larry King Cheat With His Sister-In-Law?

Larry King Divorce

Both Larry King and his seventh wife, Shawn Southwick King, filed for divorce on Wednesday, citing irreconcilable differences, and we guessed this was just another case of Larry's suspenders coming in the way of true love. But now Radar is reporting that Larry may have been carrying on a years-long affair with Shawn's sister, Shannon Engemann. Because not only was one lovely woman sleeping with a man 26 years her senior, but so was her sister! That makes perfect sense.

Radar reports that CNN employees said Shannon would often visit 76-year-old Larry at work without Shawn. "She visited him numerous times all on her own," the sources said. "And she was always very comfortable around Larry...their relationship seemed very natural." Other sources say Larry bought Shannon a $160,000 car and may have spent as much as a million dollars on her. Which we suppose is a fair exchange for hearing, "Lisa in Omaha, hello, go ahead!" in the middle of sex. According to TMZ, Shawn checked Larry's credit card statement, saw thousands of dollars in purchases from the high-end jeweler Cartier, and freaked out.

Those same CNN sources also said that Shawn, 50, the mother of Larry's two youngest children, sons Chance, 11, and Cannon, 9, rarely came to the set. (Larry also has three older children from previous marriages.) "Their relationship never seemed real [and] she barely ever visited him unless she was somehow included in his show," the CNN source told Radar. "[Shawn and Shannon] have a love-hate relationship. When you see them together, it's all hugs and kisses, but the truth is Shawn doesn't trust Shannon one bit." How To Deal With An Inappropriate Crush

Larry was also overheard saying that if he'd met Shannon first, he would have married her rather than Shawn, according to CNN sources. He also accused his wife of having an affair with one of the kids' baseball coaches. Shawn is seeking physical custody of the boys while Larry wants joint custody, so that ought to be an unpleasant battle. Shawn is also asking for three homes, one in Beverly Hills and two in Utah, in the divorce. Well. We guess Larry will have more to talk about with Tiger Woods than their respective backswings next time Tiger drops by Larry King Live.
