SIZZLER: Nick Kissie CaCee

|

Cobb

Jessica Simpson’s very best friend in the world, CaCee Cobb, was spotted getting hot and heavy with Simpson-ex Nick Lachey at an LA nightclub.

"The two were all over each other," says the eyewitness, who knows both Nick and CaCee. "Nick had his arms wrapped around her, and he was kissing her all over the side of her face…"

Sure it’s a betrayal but can you blame her? Nick is one amazing side-of-the-face kisser.
