Ashlee Simpson & Evan Ross Attend Jessica Simpson Fal l2013 Launch

Getting ready to show off some of the upcoming season's hottest duds, Ashlee Simpson hosted the Jessica Simpson fall 2013 campaign launch in New York City on Tuesday (July 30).
Looking stunning, the 28-year-old singer sported a floor-length blue dress from the line while posing with her rumored new man Evan Ross and her mom, Tina Simpson.

Speaking of Ashlee's love life, it has recently been speculated that she and Ross are a new couple since her breakup with Vincent Piazza back in November.
Adding fuel to the fire (aside from the pair appearing together tonight), Evan has been tweeting photos from backstage during Simpson's recent stint for "Chicago" at the Hollywood Bowl.
