(Cover) - EN Showbiz - Kim Kardashian says thinking about Beyonc Knowles inspires her to stay motivated when she doesn't feel like working out.

The 30-year-old bride-to-be told this month's Health & Fitness magazine that she loves her butt and does "squats and lunges to accentuate it".

But when she is not feeling very motivated she thinks of the Bootylicious singer.

"When I can't be bothered I just think Beyonc, Beyonc, Beyonc! I think her curves are beautiful," Kim gushed.

Kim is currently working out with celebrity trainer Gunnar Peterson four times a week as well as watching her legendary sweet tooth and sticking to more healthy fare.

She says that she is doing a regime focusing on strength moves and cardio intervals and eating salads and lean protein but allows herself the occasional treat, because she would "go mad otherwise".

Kim is set to marry fianc Kris Humprhies later this summer in a figure hugging Vera Wang dress and although she likes her shape, wants to make sure it is in perfect condition for when she walks down the aisle. (C) Cover Media
