Kim Kardashian: I Want “a Six Pack by Summer”

Kim Kardashian is getting her body ready for a bikini.

"I have been going sooo hard in the gym, and I really feel it's paying off!" she blogs. "My tummy is soo toned. Why is it that the top part gets ripped first and the lower part is sooo hard to tone up!? I am determined to have a six pack by summer! In a feminine way, of course."

Can you guess whose abs these are?

The 5-foot-2, 118-pound Kardashian, 28, recently opened up to Us Weekly about how she whittled her size-6 physique down to a size 2. Her routine involves "an upbeat warm-up, then upper-body cardio using 5-pound weights, a lower-body workout with squats and lunges," she told Us. She finishes it off "with an abs series and stretching."

Despite all the working out, she tells Us, "I love my curves and have to work out to maintain them. Actually, keeping my shape takes a lot more work than just doing nothing or being super-skinny. So this was about toning up, getting fit."
