Ashlee Simpson was recently spotted out on the town and spending time with Evan Ross, the son of legendary Motown singer Diana Ross, and many are speculating that the two are currently dating, according to the New York Daily News.

The two were recently spotted holding hands while leaving the Sunset Marquis Hotel on Monday night, and were seen later on Tuesday leaving Teddy's at the Roosevelt Hotel around 1:30 a.m. after a night out partying with friends. In the new paparazzi shots, Simpson looks pretty in a full-body floral pantsuit, her long blonde waves flowing down her shoulders, while Ross rocks a floor-length overcoat with dress pants and a white t-shirt.

The 24-year old son of Diana Ross 28-year old sister of Jessica Simpson also grabbed lunch together yesterday in West Hollywood, US Weekly reports. Simpson was all smiles hanging out with Ross, both of them sporting sunglasses and black rocker boots.

"Evan and Ashlee have been friends for a really long time, probably ten years," a source told US Weekly. "They know each other from the club scene and have tons of mutual friends."

Simpson's last boyfriend was "Boardwalk Empire" star Vincent Piazza, but after a year and a half of dating the couple called it quits in 2012. Simpson is mother to 4-year old son Bronx Mowgli, whom she had with her ex-husband Pete Wentz. The two have remained on good terms for the sake of their son since their divorce in 2011.

Simpson recently became an aunt once more as her sister Jessica gave birth to her second child on Sunday, a baby boy she named Ace Knute Johnson.
