Kylie Jenner caused a media frenzy on Wednesday after posting a photo of Khloe Kardashian with her "real father" Alex Roldan.

"First official photo of my sister and her dad! Like father like daughter!" Jenner wrote on February 8 on her official Instagram account, with a photo of Roldan with his arms around Khloe Kardashian.

After several media outlets reported that the youngest daughter of Kris and Bruce Jenner had confirmed the paternity of her older sister, she revealed that it was just another one of the family's pranks.

"It was a joke everyone! Lol!" Jenner wrote on Twitter.

Rodan is a hairdresser who worked with Kris Jenner in the past. He was named as Khloe's in several tabloid reports earlier this year, much to the annoyance of Khloe and Kris Jenner.

Khloe Kardashian went on a Twitter rant on January 11 following a tabloid report featuring quotes from Robert Kardashian's ex-wives that suggested Khloe was not his biological daughter.

Khloe Kardashian, 27, is taller than her sisters Kim, 31, and Kourtney, 32, and has naturally lighter hair then her raven-haired siblings. She was even seen seeking a DNA test on an episode of the family's hit E! reality show, "Keeping Up With The Kardashians."

Star magazine quoted Jan Ashley, Robert Kardashian's second wife, as saying that he had told her that Khloe Kardashian is "not really a Kardashian." It also quoted Ellen Pierson, his third and latest spouse, as saying that "Robert did question the fact that Khloe was his." The story was also posted on Radar Online, whose parent company owns Star.

"I have never heard such crap in my life," Jenner told Lara Spencer on "Good Morning America" on January 12. The video can be seen below. "I was there. I gave birth. I know who the dad was."

"We did a whole episode on this because it's the family joke because Khloe was blonde and not dark haired," she said referring to an episode of "Keeping Up With The Kardashians" where Khloe made Kris Jenner take a DNA test.

Robert Kardashian, a lawyer, died at age 59 in 2003 after battling cancer. He and Jenner, his first wife, were married between 1978 and 1990. The two also have a son, Robert, who is 24. Jenner also has two daughters, Kylie and Kendall, with current husband Bruce Jenner.

In a 2009 episode of "Keeping Up With The Kardashians," Khloe Kardashian is seen seeking a DNA test to find out if Kris Jenner is her birth mother. She talks about how she feels her mother treats her differently than her sisters, namely Kim and Kourtney, adding "someone that psychotic cannot be blood related to me."

She orders a DNA home testing kit and is seen inserting a Q-Tip into her mother's mouth.

Khloe Kardashian's E! reality show spin-off "Khloe & Lamar," which showcases her life with husband and NBA star Lamar Odom, returned for a second season in February. The two filmed episodes for it in Dallas. Odom was traded from the Los Angeles Lakers to the Dallas Mavericks late last year.
