A feast for the eyes!

Five months after giving birth to baby North, Kim Kardashian looks hotter than ever. But while Kim says that she's shed the 70 pounds of pregnancy weight by doing the Atkins Diet and exercising, Life & Style can exclusively reveal that the reality star has also been sneaking off to get secret cutting-edge cosmetic procedures to get her body back.

A source says the new mom has been seeing Dr. Simon Ourian, a Beverly Hills cosmetic plastic surgeon based at the discreet and upscale Epione clinic. She’s been getting work done, including fillers, stretch-mark treatments and a fat-reducing ultrasound procedure on her stomach that costs up to $5,000 a session.

Kim, who most recently visited Dr. Ourian on Nov. 13, gets the Coolaser treatment, which chills the skin and then uses light pulses to vaporize skin cells — removing wrinkles, scars, saggy skin and stretch marks.

“It’s popular with celebrities post-baby to reduce stretch marks and sagging in the tummy and breast areas,” an insider tells Life & Style. The Epione clinic can also use ultrasound to melt a layer of fat just beneath the skin.

While Kim's rep denies she’s being treated by Dr. Ourian, insiders tell the mag that she's going to great lengths to keep her visits a secret.

A source from the clinic shares that “Kim and other high-profile clients can sneak in through a back door” to keep from run-ins with the paparazzi. And during one trip to a laser hair-removal clinic — another of Kim’s secret weapons — she pretended to be visiting the Pilates studio next door. “She even wore workout clothes to throw off the photographers and begged them to make it look like she was going inside to work out, not to get laser treatments,” an insider spills to Life & Style.
