Simpson + Romo Reunite For Ashlee's Wedding

The 27-year-old singer and Romo attended Ashlee Simpson and Pete Wentz's wedding at the Simpson family's California home on Saturday.

It had been reported that American footballer Romo had called off his romance with the singer/actress after growing tired of her meddling father, Joe.

But they proved they were still very much in love during the wedding ceremony, reports People.com.

A source tells the publication, "They were very cozy and cute together... She was in an amazing mood and so happy her sister was getting married.

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

And Simpson's spokesperson, Cindi Berger, has continued to dismiss the break-up talk, insisting it's "not true".
