Ashlee Simpson Stars in Ad Campaign for Jessica’s New Collection

Sister, sister!

Jessica Simpson is featuring Ashlee Simpson front and center for her new ad campaign. Here's your first look at the youngest Simpson sibling modeling the Jessica Simpson Fall 2013 Collection.

The glamour shots were taken by Ellen von Unwerth in Agoura Hills, California, where Jessica was on set overseeing the photo shoot.

While Jessica recovers from giving birth to baby number two – Ace Knute Johnson, who arrived on June 30 – Ashlee will temporarily take the reins of Jessica's soon-to-be $1 billion fashion empire. She is set to unveil this season's campaign at a press party on July 30 in NYC, according to E! News.

Ashlee, 28, was clearly quite inspired by working with sister.

"Yes [I'm designing my own line]," she told Life & Style. "It will be adult. It will definitely [be different from Jessica's.]"

Can't wait to see if she’s as successful as Jess … she’s a tough act to follow!
