Wendy Williams compares bikini photos of 'The Hills' stars Kristin Cavallari and Heidi Montag on 'The Wendy Williams Show' (weekdays, syndicated), noting how Montag's recent plastic surgery has made her look much older than her 23 years of age and given her the look of an adult entertainer to boot. "Well, you know, I have to say ... Heidi looks like a hard-living porn star who's 40," Williams said. "That's not necessarily a bad thing, but she looks older." See the clip for more, including Cavallari's priceless reaction.
