Audrina, Heidi and Kristin filming "The Hills" in Beverly Hills
Wednesday March 17, 2010. Things get a little toasty on The Hills as Kristin Cavallari, Audrina Patridge, and Heidi Montag lunch together at Villa Blanca. The hot weather literally came into play as Heidi Montag began showing signs of her armpits while Audrina Patridge stayed cool in a barely there strapless dress. In between takes, a crew member sat down with the 3 girls at their table to talk to Heidi while Kristin (who noticeably is the only one actually eating food, a salad) ate lunch. Afterwards, the girls left in their cars, but it was Heidi who stole the show as she strutted her stuff on the sidewalk with extremely tight and tiny khaki shorts.
