Jessica Simpson is reportedly jealous of Cameron Diaz and her ex-lover John Mayer's current relationship. A source told US magazine: "She had her mouth open wide when she found out. She just freaked out. She thinks about him all the time. She is so not over him." Despite the Newlyweds star splitting with Mayer back in May, she is still "really jealous" of his new lover, claims the insider. First, a monkey steals her co-hosting job and now this! No one can compete with her pops, Joe, though. He's so hot it's hard for her to commit to anyone else.
