(Cover) - EN Showbiz - Kim Kardashian finds it impossible to stay slim in New York, claiming the city is "the death of [her]".

The reality TV star has recently moved to the East coast after marrying basketball hunk Kris Humphries. Kim admits she is missing Los Angeles as she maintained a much healthier eating regimen there.

"New York kills me," she told talk show host David Letterman. "I'm here for a couple of months and it's just the death of me... those nuts on the street corner... I put on an extra ten pounds every time."

Kim's sisters Khlo and Kourtney were also present for the interview, which was broadcast on Tuesday night.

Khlo finds it infuriating that Kim still looks good even when she does gain weight. She also claims the extra pounds go straight to the most famous part of her body.

"That's where all of the fat goes - right to her ass!" Khlo complained. "All she does is eat junk food, and all it does is go to her booty - nowhere else!"

Kim got married in a lavish ceremony in August.

The 30-year-old was thrilled with how the day turned out, but admits planning it was a stressful experience.

"It was a lot of fun," she explained. "I just had no idea how hard it was to plan a wedding... if that was my job, I'd go crazy." (C) Cover Media
