Simon Cowell and Paula Abdul must be trying to get that “old thing” back. The two TV personalities, who were co-judges on “American Idol,” shared a quick kiss yesterday afternoon (Sun. May 8) as they reunited at the Los Angeles auditions of their new show the “X Factor.”

Fox officially confirmed yesterday that Paula Abdul will be joining the X Factor judge’s panel alongside Simon, Cheryl Cole and Antonio “L.A.” Reid. And Simon says he’s thrilled to have his old friend back.

“We almost weren’t going to do the show,” Cowell said. “This show would never have been the same without Paula and I can’t believe I am saying this – I have missed her a lot, and I am thrilled she’s on the show.”
