Kim Kardashian and Kanye West are reportedly planning to have another baby.

The 33-year-old reality TV star and the rapper only welcomed their first born, daughter North, into the world in June, but are already considering extending their family as they are concerned time may not be on their side when it comes to conceiving. "They are discussing having another baby right away. It's serious. [Kim] is well aware that she's getting older, and that if she wants to have a bigger family, then she needs to get it done," a source told RadarOnline.

Kim has been taking part in a gruelling exercise regime and sticking to the Atkins diet in a bid to return to her post-baby weight, but she's now considering ditching the tough fitness techniques. "Kim is telling Kanye that she doesn't think it makes sense to gain pregnancy weight, lose it, and then gain it all back again. She's starting to think she might want to just suck it up and be big and pregnant in one long go and then lose the weight once and for all. Kanye likes Kim at any size, so that part doesn't matter to him but he loves the idea of having another baby soon," the source explained.
