Jessica Simpson threw Tony Romo a 28th birthday party he’ll never forget: She licked cake off his face, reports.

The PDA-packed bash took place Saturday night at Suite, a lounge in Dallas, where “she sang him ‘Happy Birthday,’” Kyle Kearbey of, the website for Dallas’ D Magazine, told

The two really seemed to enjoy the cake, which was in the shape of a Dallas Cowboys star and had Romo’s No. 9 jersey number on it.

“They were kissing with lots of messy cake!” adds Kearbey. “Jessica had cake all over her hands and was licking her thumbs.”
