Jessica Simpson Enlists Sister Ashlee for Tween Fashion LIne

Jessica Simpson has a new baby y'all! The fashion mogul, whose clothing line topped $1 billion in sales last year, is creating a new collection catering to tweens. And she's enlisted the help of little sister Ashlee in the design process.

The line will include sportswear, jeanswear and activewear, mixing elements of Jessica's "girly, playful" style with Ashlee's more "rocker edge."

The Simpson sisters' collection is expected to launch at the end of the year, reports Women's Wear Daily, and young fashionistas can select from various types of denim, graphic tees, pullovers, shrunken knits, leggings, hoodies and footwear.

"I'm excited to bring my sister to this division," big sis Jess tells WWD, "because she brings a savvy rocker edge that defines today's tweens."

"My goal will be to design clothes that will help inspire young girls to express their personalities and creativity through fashion," adds Ashlee.
