The Hills star Kristin Cavallari has worked and worked on her bikini body, and now it is absolutely sexy. 'I looked really fat,' Kristin Cavallari said, reflecting about seeing her self on The Hills. I would argue with that, because I think she was pretty sexy to begin with. I don't think she 'fat' would be the right way to describe her bikini body. Now however, she has used kick boxing to tone and tweek her body to where it is now. I will say though, you do notice the results and it does look good.

Kristin Cavallari recently sat down with People Magazine and talked about her perception of herself on television. 'I remember filming The Hills and I saw a photo of myself in a bikini and thought I looked really fat, and I went on a crazy diet,' Cavallari told People magazine. 'It's hard when people judge you.' Kristin Cavallari talked about what she did and didn't do to get the body she has now. 'I worked out with my trainer three times a week then did cardio on the treadmill for 40 mins. But the biggest thing for me was cutting out alcohol; when I'm hungover, I eat whatever I want,'

Since lingering in Lauren Conrad’s shadow on The Hills, Audrina Patridge has moved on to bigger and better things. The new star of reality show Audrina is one of those envy-provoking girls whose metabolism magically zaps up all the liquor, froyo, and California burritos it wants. Although Audrina’s always been thin, she still works hard to maintain that slim muscular build. Audrina teased us with how she got her bikini babe body.

Audrina Patridge gave some insight to her slim and sexy bikini body."My mom has a good body, so I’m lucky to have the body I have. I’ve always been in shape; I’ve danced since I was really little and I was on the swim team," she told Maxim. But with that said, she says she is still a "health buff" and works pretty hard to stay sculpted. "I’m not going to the gym to lose weight, but to get definition in my arms, butt and legs.” I think it worked, just look at her sexy bikini body!

The Hills star Lauren Conrad partied in a black bikini at Tao Beach at the Venetian Hotel and Casino in Las Vegas on Saturday, but she left a little to the imagination with a cover up that she wore. "The Hills" just celebrated its final season, and Lauren and Kristin Cavallari have made amends after a tumultuous friendship (they both fought over Stephen Colletti and dated Brody Jenner.) Cavallari explained, "We are not going to lunch together and I don’t have her phone number, but we are cool."

Back to the issue of Lauren Conrad’s fashion taste, I am not sure how to feel about what she was wearing (see pictures below). As far as what she is wearing, yeah it looks okay, not great, but okay. I feel like there are a lot of other outfits she could have chose to wear that would have looked a lot better then that. Also, I do not know if that was really the most appropriate thing to be wearing out to a club, but hey what do I know, I am not Lauren Conrad.
