In this week's issue of Us Weekly, Kourtney Kardashian reveals her svelte post-baby body. The reality star, 33, has dropped an impressive 44 pounds since giving birth to baby Penelope in July.
And among those admiring her stunning weight loss is sister Kim Kardashian, who recently announced her own pregnancy.
"How incredible does Kourt look!? She has lost 44 lbs in 6 months since giving birth to Penelope and looks better than ever," Kim wrote on her Celebuzz blog Thursday. "She is an inspiration to me! While we were in Miami we would always work out together and keep each other motivated and I am so proud of her!"
While Kim is only about three months pregnant, she is reportedly already thinking about her own post-baby weight loss. A pal told HuffPost Celebrity that the 32-year-old would love to score a Weight Watchers deal similar to Jessica Simpson's. "She plans to stay healthy during her pregnancy, but even so will gain baby weight that she would love to be paid to lose," said the insider.
In another post on her blog, Kim assured fans that she was working with a trainer to stay fit during the coming months. "Tracy Anderson is keeping me in shape!" she wrote. "She is helping me make the adjustments necessary to keep me feeling happy, healthy and most importantly create a workout plan that is safe for the baby."
