Kim Kardashian’s famous hourglass figure has grown by 28 lbs since she started dating Kanye West – and he loves every inch of it.

Kim Kardashian, 31, has slowed down her hardcore exercise regime and now weighs more than she ever has at around nine stone.

She has gone up to a size 12, having previously been a size 8, and she is happy to skip trips to the gym in favor of staying in bed with Kanye West.

A friend of Kim Kardashian’s told Heat magazine: “Instead of hitting the gym at 6:00 a.m., she’s finding herself staying in bed with Kanye and really letting her guard down.”

Her rapper boyfriend is said to be happy with her new shape and he has been encouraging her to diet less.

Kanye West has never made a secret of his love of curvy girls and he often references the feminine form in his songs.

He raps on Good Life: “Welcome to the good life, where we like the girls who ain’t on TV ’cause they got more ass than the models.”

With Kanye West having a healthy appetite for food, his relaxed attitude has rubbed off on Kim Kardashian  too.

A friend told Heat magazine: “She’s normally ruthless when it comes to diet and exercise, but since she met Kanye her discipline has gone out the window.”

The fact that Kim Kardashian makes a living by posing in her swimwear means that even with Kanye West’s support, she is still a little self-conscious about her weight gain.

Kim Kardaashian said earlier this month: “I’m hoping to slim down a little bit, and I’m not afraid to say it.

“I think everyone goes up and down in whatever that comfortable love-relationship phase is, where you like to eat out, but now it’s time to get it together again.”
