The Lauren Conrad Collection: Coming This Fall!

The Hills star Lauren Conrad (in her own design) and BFF roommate Audrina Patridge (in Jay Godfrey) hype up the upcoming season of their reality TV series on TRL on Monday in New York City.

As you know, Lauren has been busy designing her very own fashion line, the Lauren Conrad Collection, which is scheduled to debut on Sept. 15.

And why does Lauren look so great? “I’ve cut most carbs from my diet,” she has said. “and I work out with a trainer two days a week and hike when I can. I don’t think I look as much like a beach girl as I used to. I think I’ve just grown up.”
