Pop star Ashlee Simpson has sparked rumours of a blossoming new romance with Diana Ross' son Evan after they were snapped holding hands in Los Angeles.

The Pieces of Me hitmaker, who divorced rocker Pete Wentz in 2011, was spotted leaving Teddy's at the Roosevelt Hotel with Evan Ross in the early hours of Tuesday (02Jun13).

In photographs obtained by x17online.com, Simpson is featured rocking a floral maxi dress and a shy smile as she hops into the back seat of a waiting car with the 24 year old.

The singer split from Boardwalk Empire star Vincent Piazza in November (12), while musician/actor Ross has previously been linked to Rita Ora and model Cora Skinner.
