Lauren Conrad Sweats It Out In A Pair Of Leggings

Lauren Conrad must have been burning up today when we spotted her working out in a pair of long black leggings, but the former Hills hottie was all smiles when we took her picture!

So now that she's no longer on a hit reality TV show, what's she been up to? In addition to working on her fitness, blogging about beauty and fashion and spending time with her pooch Chloe, LC recently unveiled her new accessory line with BlueAvocado XO(ECO). She created 20 travel and cosmetic accessories which are made with Repreve, a fabric made from recycled plastic bottles.

“I wanted to be part of the solution, not the problem,” Lauren told People. “As a designer, I hope that my choices can raise visibility around the importance of environmental sustainability and start to drive change with my fans. And what a great way to reuse those bottles we recycle every week."
