Kim Kardashian

Kim Kardashian is known for the way she fills out her jeans, and she wants to help you fit in yours with her new workout DVD. Would you believe two of the three discs focus on the butt?

"Everyone wants to fit in their jeans by the weekend and look good," says the reality star, who stopped by TVGuide.com earlier this week to talk about Fit In Your Jeans By Friday.

The shapely celebrity explained she made the three-disc set (Butt Blasting Cardio Step, Ultimate Butt Body Sculpt and Amazing Abs Body) because it gave her the motivation she needed to work out.

Kardashian also reveals some of her favorite moves (she says she likes to "stick with my lower body"), what kind of result she has seen since making the DVD, and whose "big butt" she loves.  

As a side note, we too were fooled by the weekend wig picture she posted on Twitter — and fully expected a blonde Kardashian to come through the studio door. (You can also follow TVGuide.com on Twitter for breaking news and scoop!)
