It seems like Kim, Khloe, Rob and Kourtney Kardashian may just have a half sister overseas that they never knew about. A 21-year-old named Emilia C. Morales who lives in England is claiming to be the love child of Robert Kardashian.

It seems that the woman who is half-Ecuadorian has been reportedly been running around the UK telling everyone that she is a Kardashian, according to Ok! Magazine.

Hollywood Life reported that Morales alleges that her mom had an affair with Robert Kardashian when he stayed in London for a business trip. As time has passed she now believes that she is the sister to Kim, Kourtney, Khloe and Rob Kardashian.

A source said, "This has a tinge of believability, and the girl does have the look of a Kardashian."

But it seems like the Karashians are not really worried about welcoming their "sister" into the family. An insider revealed, "The family is extremely wary, because all these weirdos have been crawling out of the woodwork for years making crazy claims."

The source added, "People are always looking to cash in on them, so they've lost count of the number of times they've had to roll their eyes or defend themselves."

"The family doesn't see any reason to humor Emilia." the insider adds. "They're not dignifying these claims."
