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,'

The Hills star and bikini babe Kristin Cavallari is taking her flawless bikini body to the dunes of Malibu! The former reality star was spotted flaunting her famous assets in a skimpy purple bikini for a special photo shoot in Malibu on Wednesday, May 25. The blonde beauty – who recently got engaged to Chicago Bears quarterback Jay Cutler – pouted for the camera while she wrapped a white robe around her legs to cope with the chilly sea breeze.

During the shoot, Kristin Cavallari had a little fun by doing a quick role reversal with the shoot’s make-up artist. “Love shooting with Kristin Cavallari,” tweeted the make-up artist, Charlene K. “She does my make-up every time!” Sounds like it would have been a fun photo shoot to be at. Seeing Kristin Cavallari in a bikini would have been good enough as it is.

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.
