Kourtney Kardashian Loses 44 Pounds

Kourtney Kardashian has shed 44 pounds over the past six months.

The 'Keeping Up With The Kardashians' star - whose sister Kim, 32, confirmed her first pregnancy this week - has revealed she has lost all of her baby weight since giving birth to her second child Penelope last July after adopting an intensive fitness regime.

The 33-year-old reality TV star told US Weekly magazine: ''It was harder to lose weight the second time around. I gained 45 pounds with Penelope.''

Kourtney - who also shares a three-year-old son Mason with long term boyfriend Scott Disick, 29, - says she now weights a trim 106 pounds and credits celebrity personal trainer Tracy Anderson's 90-minute dance-focused workouts and portion control for helping her to regain her pre-pregnancy figure.

But despite being thrilled with her new body, the mum-of-two insists that she wasn't obsessed with dieting and is more concerned with keeping her children happy.

She said: ''This time, the focus is really on being a mom and being present, knowing my priorities.''

Kourtney previously admitted to going to extremes to lose weight after her first pregnancy and even fainted due to a drastic diet she adopted to slim down quickly for a photo-shoot.

She said: ''I was just running down the beach like I always have been lately. And then I just woke up. I've been obsessing about this weight thing a little too much. I'm so embarrassed that I punished my body for a photo shoot.''
