(Cover) - EN Star Style - Kristin Cavallari will intensify her gym routine two months before her wedding.

The former Hills star is marrying Chicago Bears quarterback Jay Cutler next spring, and the stunning star wants to wow in her wedding gown.

The blonde beauty insists she'll continue with her normal work out regime and then up her game as the big day approaches.

"I'll probably keep up my regular gym routine for the coming months... until spring. And then probably two months before [the wedding] I'll go at it harder," she explained in an interview with People magazine.

The 24-year-old also revealed she'll be making changes to her diet as her nuptials get closer. The slim star insists she'll give up her vice of alcohol in preparation.

"If I eat really healthy, then I'll probably cut out alcohol for a month or two before my wedding," she said.

Kristin says her current beau makes her feel confident in her own skin. She never felt "skinny enough" when dating former lovers.

"He makes me comfortable. I've dated other guys, and I've felt like I'm not skinny enough. But with Jay, I've always felt really comfortable in my skin," she gushed.

Kristin has revealed what kind of wedding dress style she'd prefer. The stylish reality TV personality hasn't got too far with planning her overall dress design though.

"All I know is, strapless. That's as far as I've gotten!" she added. (C) Cover Media
