Kim Kardashian is planning a honeymoon baby

Los Angeles - Kim Kardashian wants to get pregnant on her honeymoon.

The Keeping Up with the Kardashians star, who will reportedly legally marry Kanye West this week ahead of their lavish nuptials near Paris on 24 May, is eager to give their 11-month-old daughter, North West, a sibling as soon as possible.

A source told Us Weekly magazine: "She wants to get pregnant right after the wedding. She wants her kids to be close in age."

North is set to celebrate her first birthday on June 15, and Kim, 33, has spent much of the last year following a rigid diet and exercise plan to lose the 50 pounds she gained during her first pregnancy.

Kanye, 36, has developed a very close bond with his baby girl, who recently started saying a few words.

An insider said: "She has recently started saying 'Daddy.'"

Kim previously admitted that North made her want to have "a million" children because she is the perfect baby.

She said: "I've always wanted about six [kids]. After having [North], I would have a million."

Meanwhile, the reality TV star was spotted making a few final arrangements for their upcoming wedding in the French capital on Wednesday, where she was joined by tennis star Serena Williams.

The brunette beauty fuelled speculation that she will walk down the aisle in a custom-made Balmain creation, as she visited the design house's showroom, but she may also have been finalising her dress for the Met Ball in New York City on Monday.
