Two people have reportedly come forward claiming to be long-lost siblings of the Kardashians.
An Los Angeles woman and a New York man claim to be the children of the Kardashian family patriarch Robert Kardashian, who died in 2003.
Rumours of Robert having had other children besides the now famous Kim, Khloe, Kourtney and Rob, first surfaced in 2013, when a British woman named Emilia Morales claimed to be his daughter.
Those claims have since been shot down, but a family friend told Radar Online that these two newcomers are "demanding answers", and "it's sent the entire family into meltdown".
"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," said the source.
Jenner was married to Robert from 1978 to 1991, when she married Bruce Jenner, now known as Caitlyn.
Robert did not remarry until 1998, when he married Jan Ashley. He was later married again in 2003, to Ellen Pierson.
