'The Hills' stars Lo Bosworth and Audrina Patridge were spotted by photographers! The two were filming for their TV series . Check out the outfits, who's sexier? The two look happy, and enjoying the nice weather of California.

Audrina Patridge dons a nice "Punk’s Not Dead" t-shirt, sunglasses and faded jeans with black boots. Lo Bosworth looks fab and very sexy with her cream coloured top, and gray skirt. Speaking of Miss Bosworth, her pal Lauren Conrad recently told the press that Lo will not star the flick adaptation of her book "L.A. Candy". (Photo Credit: RIV/Fame Pictures)
