Kourtney Kardashian Gained 45lb Of Baby Weight

Kourtney Kardashian admits to gaining 45lb of baby weight Wenn

Kourtney Kardashain has admitted to gaining 45lbs (3st, 2lbs) when she was pregnant with her daughter Penelope, but says that she's not too worried about losing the weight just yet.

Kourtney, who gave birth six weeks ago, wasn't quite as relaxed when her son Mason, now two, was born.

Back then she went on a full-on health and fitness kick so that she could get in shape for a bikini shoot - and lost 33lbs (2st, 3lbs) in just three months. But she pushed herself so hard that she fainted after a run on the beach.

At the time she said: "I'm so embarrassed that I punished my body for a photo shoot. I've been obsessing about this weight thing a little too much."

This time round, Kourtney is taking her time - and, although she's eating healthily, she's not prepared to deprive herself.

She told US Weekly: "I gained nearly 45 pounds. I'm 5 feet tall, so that's a lot."

She added that she's 'not really' thinking about losing the weight just yet but said: "While I'm here around the house, I just eat healthily."

She also told the magazine that she had a 'really easy' delivery and pulled her daughter out herself - just like she did with Mason.

She explained: "I did! She was coming out, and I was thinking, I should pull her. With Mason, I had no idea I was going to do that. This time, I thought, this is what I'm supposed to do."

There said that there's even a chance that Penelope's arrival might feature in the new series of Keeping Up with the Kardashians as her partner, Scott Disick, recorded some of it on his iPad!
