Khloe Kardashian's younger sister Kylie Jenner confirmed the star's biological father by posting a photo of the two on Twitter.

The rumour mill went crazy last month with reports that Robert Kardashian is not her real father and various men were accused of having affairs with her mother Kris Jenner resulting in Khloe. 

In addition to O.J Simpson, Alex Roldan was also claimed to be her father after he reportedly had an affair with her mother, who he has known for 30 years.

While Khloe blasted the rumours as "ridiculous," her sister Kylie saw the funny side of the drama and posted a picture of Khloe and Alex posing together on Twitter.

Along with the image, Kylie wrote the caption: "First official photo of my sister and her dad! Like father like daughter!"
