Jessica Simpson

Jessica Simpson is reportedly jealous of ex boyfriend John Mayer and his new love Cameron Diaz. According to reports Simpson is still not over Mayer.

Mayer and Simpson dated for 9 months before splitting in May 2007. Since then she has not been romantically linked with anyone.

“She had her mouth open a mile wide when she found out. She just freaked,” a source said of Simpson when she heard about Diaz and Mayer’s relationship. “She thinks about him all the time. She is so not over him.”

But Mayer has seemed to move on without any qualms. He and Diaz spent time together in New York where sources say they got “very cozy” and claim the new couple is very “happy.”

- Aww! She probably isn’t over him yet, but it takes time. Keep your chin up, Jess =)
