Khloe Kardashian has shot down speculation she is planning to undergo fertility treatment in a bid to start a family.

The TV personality has already had to address rumours she is not a true Kardashian this month (Jan12) amid allegations late lawyer Robert Kardashian is not her biological father, and now she's facing another gossip storm as reports suggest she is interviewing fertility doctors after failing to fall pregnant with husband Lamar Odom's child.

But the 27 year old has taken to Twitter.com to rebuff the reports, insisting she would be open and honest if she was undergoing treatment.

She writes, "Because there seems to be much speculation, here is my statement... I am not at this time in my life considering any type of fertility treatments. If and when I do, I will shout it from the rooftops but for now its in God's hands."

Basketball player Odom and Kardashian wed in 2009 and shortly after the big day, the reality TV star confessed she was hoping to become a mum in a year, telling OK magazine, "We definitely want to have children. But I feel like we just got married. In my head, I'd love to settle in and find a house first. I'd like to wait a year... but I would also be thrilled if it (pregnancy) happened now."
