Is a new summer romance blossoming for Ashlee Simpson?

The pop singer and single mom, 28, has been spending time lately with Evan Ross, 24, the actor and musician son of Diana Ross.

The pair were spotted holding hands as they left the Sunset Marquis Hotel in Los Angeles on Monday. They later were spotted at Teddy’s at the Roosevelt Hotel, where an onlooker says Simpson showed off some sexy moves for Ross to Whitney Houston’s “I Wanna Dance With Somebody.”

The next day Simpson and Ross showed up for lunch together at West Hollywood’s Cafe Med.

A rep for Ross, who is a familiar face on the L.A. club scene, had no comment when asked if the pair are dating. A rep for Simpson – who amicably split with Vincent Piazza last November and is mom to son Bronx, 4½, with ex-husband Pete Wentz – did not reply for comment.
