L.C. Dishes on Frenemy Heidi

Reality starlet Lauren Conrad is giving "Extra" the scoop on her life in "The Hills" -- offering dating advice, giving us a sneak peek of her Emmy designs -- and opening up about why her relationship with Holly Montag won't help her patch things up with Holly's sister Heidi!

L.C. rekindled her friendship with Holly on "The Hills" last night -- but will her newest girlmance lead to reconciliation with former BFF, Heidi? "No, I don't think so," Lauren demurred. "Holly was a really good friend of mine when she lived here." And the saga continues.

Conrad will be creating dresses for Emmy trophy presenters -- and she's giving "Extra" a few clues to her red carpet designs. "My dress is long and flowy. I want more of a Grecian look, so I will do my hair back and kind of messed and put some braids in."

Thanks to "Extra's" fan cam, Lauren has the answer to the question everyone wants answered: How do you date in Hollywood? "Don't do it on TV," Lauren answers, laughing. "I think just have fun with it."
