Most Hollywood moms start stressing about losing their baby weight even before leaving the delivery room. But Kourtney Kardashian isn't like most women.

Instead of clocking hours at the gym to shed the 40 pounds she put on during her pregnancy, Kourt has been singularly focusing on her 7-week-old bundle of joy, son Mason Dash. "It's been hard to find time to work out," she told Life & Style during an exclusive interview on Jan. 29. "All I want to do is spend time with Mason."

The Keeping Up With the Kardashians star decided to open up about her struggle to slim down after a tabloid magazine used heavyhanded Photoshopping to make it appear as if she'd regained her svelte pre-pregnancy figure just one month after giving birth. A disgusted Kourtney, 30, says that dream body is, well, just a dream. "Losing the weight has been a lot harder than I thought," she says. "I've lost 25 pounds so far. I still have 15 more to go."
