Kylie Jenner reportedly agreed to a paternity test to prove her partner Travis Scott is the father of her daughter Stormi.
The 'Keeping Up With the Kardashians' star's ex-boyfriend Tyga - whom she split from in April last year - has been suggesting that the two-month-old tot belongs to him throughout the 20-year-old reality TV star's pregnancy and shortly after the birth.
In a bid to put the rumours to rest once and for all, the brunette beauty agreed to have the DNA test done - under the condition that Tyga never spoke of it again.
A source told The Sun newspaper: "Tyga has been demanding a paternity test throughout Kylie's pregnancy but she wouldn't hear of it.
"She still cares for Tyga but this isn't something she ever wanted to agree to.
"Kylie begged him to back off because she didn't need the embarrassment.
"The last thing Kylie wanted was everyone to think she might be hooking up with two men during the time she conceived. She didn't want her millions of fans questioning who the father is. It's hard enough being a young, unmarried, pregnant mother without adding the notion, 'Who is the father?'"
Kylie found out the result of the test, which proved baby Stormi belongs to her current boyfriend Travis, just before she posted a close-up shot of the tot on March 23.
However, the make-up mogul is said to be fuming with Tyga, 28, as he took to his social networking sites just days later to address rumours that he's Stormi's dad - despite the former couple having the agreement that it'll never be spoken about.
He said at the time: "I've never said anything about someone else's child or family insinuating my involvement; and will never do so. Please, Stop spreading false stories and attacking people's families. I have nothing to do with any of that. People should be able to live in peace. (sic)."
Kylie dated Tyga for two years before they split at the beginning of April last year and the reality TV star was spotted getting cosy with Travis, 25, at Coachella.
Travis is listed on Stormi's birth certificate as her biological father.
