Showing off their business savvy sides, Jessica and Ashlee Simpson joined together to sign autographs for their joint clothing line at Macy’s in Costa Mesa, CA on Saturday (November 10).

Thanks in part to her sixty pound post-pregnancy weight loss, first time mama Jess looked stunning in a black leather jacket while she and her lil' sis shared a few laughs and greeted their many awaiting fans.

Prior to the meet 'n greet, an enthusiastic Jessica tweeted, “Hey everyone! I'll be at Macy's South Coast Plaza with @ashleesimpson from 1-4 today! See you there!”

This was the sisterly duo’s first public outing together since news broke that their parents were divorcing - after which ugly rumors emerged suggesting that their father, Joe Simpson, preferred the fellas.

As previously reported by GossipCenter, Jessica and Ashlee's mom, Tina Simpson, filed for divorce back on September 24 after being married for more than 30 years.
