Billy Joel is single no more as a representative for him has confirmed that the music star is now dating actress Alex Donnelley, who is best known for originating the role of Diane Jenkins on the popular daytime soap opera "The Young and the Restless." The confirmation comes a month after Billy and his third wife Kate Lee confirmed their separation.

While the representative doesn't elaborate on Billy and Alex's romance, New York Post reports the twosome first met through friends backstage at his recent Washington, DC, concert. "The two hit it off immediately," an insider tells the publication. And since that time, Alex has been visiting Joel at his home in Sag Harbor, "where they go boating or ride around on Joel's custom motorcycles."

Billy Joel is a rock musician, singer-songwriter, and classical composer. He has one daughter named Alexa Ray Joel from her marriage to second wife Christie Brinkley. His first wife was his business manager, Elizabeth Weber Small.

Back in mid June this year, Billy and his third wife Katie Lee, who is a television food critic and chef, had their representative confirming, "After nearly five years of marriage Billy Joel & Katie Lee Joel have decided to separate." The representative, furthermore, stressed "This decision is a result of much thoughtful consideration. Billy & Katie remain caring friends with admiration and respect for each other."
