American reality television star Kim Kardashian and rapper Kanye West are reportedly planning to expand their family.

According to Yahoo! Celebrity, the 33-year-old Keeping Up With The Kardashians star and West would try to have second child after getting married.

It was recently reported that the couple will walk down the aisle in Paris, on 24 May.

"She wants to start trying by the end of the year - even though she hated being pregnant," the source claimed. "She's so besotted with North that she says she's totally forgotten the awfulness of being pregnant and how much she struggled."

"Kim has such a big family that she feels it's really important that there isn't a huge age gap between North and her siblings," the insider added.

"She's got her body back and loves being slim and voluptuous, but she's going to relish it for a few more months and then try for another child after the wedding, even on honeymoon," the source continued. "Kim says it'll be the most romantic thing ever and that's what they've been talking about a lot."

The 36-year-old singer welcomed daughter North with Kardashian in June.

Meanwhile, she had previously revealed that Atkins diet is the secret to her post baby body.

"I've actually been doing the Atkins diet & luv it," she tweeted to a fan.

"Kim Kardashian wanted a balanced and effective way to lose weight following her pregnancy and she chose Atkins," Colette Heimowitz, Vice President of Nutrition for Atkins Nutritionals, Inc., told ABC News, "She ate lots of lean proteins, veggies, fruits, and healthy fats like avocado and nuts. She experienced previous success on the plan, and knew she needed something that works."
