The Kardashians might have a long lost brother and sister.

Another day, another Kardashian family scandal, huh?

TV’s most famous family is said to be reeling at reports that a woman and a man, from LA and New York respectively, have claimed they are Robert Kardashian Snr‘s long-lost children.

The claims that the late lawyer, who died of cancer in 2003, fathered two children in secret has expectedly thrown the household on an “emotional rollercoaster”.

“Another woman from LA and a New York man are claiming to be Robert’s kids and demanding answers -- it’s sent the entire family into meltdown," a family friend told The Sun. “If it’s true, they would have been conceived after he left Kris (Jenner), but the emotional rollercoaster these claims put on the family are horrific.”

Robert Snr married "momager" Kris in 1978. Together they had four children, namely Kourtney, Kim, Khloe and Robert Jnr. After his divorce from Kris in 1991, he married Jan Ashley and then Ellen Pierson.

Curiously, this isn't the first time rumours of a secret love-child have emerged since the father's passing. In 2013, the rumour mill was whipped into overdrive over claims that he had a secret daughter named Emilia Morales, who was the product of an extra-marital affair with a woman on a London business trip.

While the gossip was never directly addressed by the Kardashian clan, a source at the time told The Sun that “Kris is confident these are just as false as the Morales case, but in the meantime it’s sent them all into uproar.”

Hmmm. It looks like we'll just have to wait and see about this one, folks.
