Ashlee Simpson is dating 'Boardwalk Empire' star Vincent Piazza.

The 26-year-old singer-and-actress - who split up with husband Pete Wentz after just over two years of marriage in February - has been spotted kissing and holding hands with the actor in New York.

It is not the first time Ashlee, who has two-year-old son Bronx Mowgli with former 'Fall Out Boy' star Pete, has spent time with another man since her break-up - she has also enjoyed the company of D.R.U.G.S. front-man Craig Owens, who is a good friend of her ex's.

However, in March Ashlee was seen holding hands with her 32-year-old estranged husband, sparking speculation the pair had reconciled as she "lovingly leaned" on him while out.

A source said: "Ashlee and Pete held hands, and Pete especially looked very happy. While waiting for their drinks, Pete had his arm around Ashlee and they definitely looked like a couple again.

"Ashlee kept smiling and lovingly leaned on Pete."
