Jessica Simpson and Tony Romo are still together

Jessica Simpson and Tony Romo were spotted together Friday on a sushi run in L.A., and later during Ashlee's rehearsal dinner.

"They were very cozy and cute together," said a source. "She's definitely not mourning John Mayer! She was in an amazing mood and so happy her sister was getting married."

"They were kissing and holding hands throughout the night," added the insider. "He was very sweet to her. They were very much a couple."
