A sex tape featuring Kylie Jenner and Tyga was reportedly uploaded online.
Kylie Jenner
It has been claimed that an intimate video of the pair was seen on the 26-year-old rapper's official website, Tygasworld.com, for approximately 30 minutes before it was taken down.
A source said: "Tyga will not sign off on releasing it to the masses, but Kylie is scared that a sex tape could get in the wrong person's hands with one of his buddies and they could put it online to embarrass her.
"She is freaking out that something like that will happen, especially if she starts bashing Tyga in any way. If the Kardashians bash him, it would open the door for something like that to happen. He has a lot of power right now."
One Twitter user appears to have secured the footage before it was taken down, writing on the social media site: "Guess who got the Kylie Jenner sex tape before it was deleted from Tyga's website."
However, if it is found that the 'Rack City' hitmaker was behind the leak, he could be in hot water as it could possibly be considered under California's new revenge porn law.
Californian lawyer David Pisarra told HollywoodLife.com: "Tyga would need written consent from Kylie before he can release a sex tape of the two of them. Any sex tape released without Kylie's consent would possibly fall under California's new revenge porn law which prevents exes from releasing private material after relationships end."
Meanwhile, the 'Keeping Up With The Kardashians' star has already reportedly moved on from Tyga and is now dating another rapper, PartyNext Door.
A source told The Sun newspaper of their romance: "Their relationship started quite suddenly but it just feels right. They are mad for each other. She doesn't know why she wasted time with Tyga.
"Kylie's family found the eight-year age gap with Tyga a bit weird, especially as they got together before she turned 18 last year. PartyNextDoor is much better as he's only four years older than her."
