The 28-year-old reality star - who married basketball player Lamar Odom in September 2009 - has decided to put her baby plans on hold for now because she is "too busy" since landing a co-presenter job on `The X Factor` USA.

A friend of the Kardashian family told HollywoodLife.com: "Khloe is putting her fertility treatments on hold for the time being. She is just too busy right [now] with `The X Factor`. When things calm down she will resume her treatments."

Despite her decision, Khloe - who is hosting the talent show alongside Mario Lopez - is still desperate to become a mother, and Lamar is said to be backing her decision 100 per cent as he is also "super busy" plying his trade with NBA team Los Angeles Clippers.

The friend added: "Lamar is pretty much supportive of whatever she wants to do. Plus, he`s super busy right now too. They aren`t worried. Khloe believes that one day she will be a mom, just not right now."

Khloe has been undergoing fertility treatments in the hope of starting a family with Lamar and while she has made no secret of her desire to have babies, the `Keeping Up with the Kardashians` star has previously admitted feeling under pressure to conceive.

She said: "People keep saying, `Why aren`t you pregnant yet?` That`s what scares me, when people are like, `Did you go to the doctor? Do you know if everything`s working?` It`s nerve-racking. Sometimes I feel like I`m letting everyone down."
