The Kardashian family is already a big bunch, with four kids and lots of half and step siblings, but could there be another secret sister somewhere out there?

Ok! Magazine claims that Emilia C. Morales, a 21-year-old living in the UK, is the secret love child of Robert Kardashian, who fathered her when he was visiting London on business.

A source for the magazine reports, “This has a tinge of believability, and the girl does have the look of a Kardashian,” although the Kardashians are understandably suspicious of these claims.

“The family is extremely wary, because all these weirdos have been crawling out of the woodwork for years making crazy claims,” says the tipster. “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.”

Emilia’s reported refusal to cough up DNA is not helping the case for her paternity, although her own admission that she’s not into the rumors is probably an even better indication that she’s not going to be joining the Kardashian Christmas card any time soon.

I dont need to clear up some nonsense that someone made up about me, it's OBVIOUSLY lies I dont understand how anyone could believe this,” she tweeted yesterday. According to Emilia, an acquaintance with dreams of becoming a reality star has been spreading this rumor about her in the hopes of inking a reality deal.

While Emilia doesn’t seem to have a hand in this frustrating situation, this isn’t the first time the Kardashians have been the subject of paternity rumors — earlier this year, model Michael Girgenti claimed to be the father of Kourtney Kardashian’s son, Mason, an allegation that was quickly dismissed — first by anyone with a set of eyeballs, and secondly, by a DNA test, which proved Scott Disick to be Mase’s dad.
