Kristin Cavallari won't talk about Audrina Patridge's plastic surgery. 

Us magazine asked Kristin what she think of her "Hills" costar's physical transformation since the first season of the reality TV show.

Cavallari laughed. "I'm not commenting on her plastic surgery," she then told Us. 

But in this recent video from the junket of "Sorority Row," Audrina also makes light of all those silly rumors about her chin implant, cheek implants and nose job.

Notice she does not mention breast implants. Hmmm.

What do you think Audrina has had done?
