Fed up: Khloe Kardashian, pictured with husband Lamar Odom declared herself fed up with 'false stories' on a web post on Wednesday

 As a Kardashian, she is used to having details of her personal life thrust into the spotlight.

But youngest sister Khloe has become increasingly frustrated with what she has deemed 'false stories' in U.S. tabloids about her marriage and efforts to become pregnant.

The 28-year-old took to her Celebuzz page to refute recent reports in a strongly worded post, saying: 'These blatant lies are distasteful and shameless.'

'It is disgusting that Life & Style and InTouch magazines continue to print these false stories about my life: the status of my marriage, false reports about a miscarriage, the horrible lie that my dad is not my biological father, jealousy over my sisters’ lives, etc,' she writes.

'It is a complete waste of time to address these reports every time they print these ridiculous and absurd tabloid stories, but not only are these stories untrue, they’re also unfair to the people who buy the magazines expecting to read accurate reports.'

Khloe is referring to allegations that the late Robert Kardashian is not her biological father, claims vigorously denied by her mother Kris Jenner.

A magazine also this week published a picture of Khloe under the caption 'Cheating Scandals' along with the allegation that she and husband Lamar Odom had split.

Last year, the star, who has made no secret of her desire to have a baby, was forced to deny rumours that she and Lamar had suffered a miscarriage.

'Anyone who pays attention to these things can easily see the incredible bond that everyone in my family shares,' she adds in the post. 'I’m happily married to a wonderful man and fall in love with him more and more each day, and we’ll have a baby when god wants us to and when the time is right.'

Later, Khloe reiterated her point on her Twitter page, posting: 'People say the truth hurts, but the truth is not what makes the tabloids money. I will admit, the false might cut a little deeper. At least the truth I can respect and grow from.'
