Kylie Jenner's Twitter page has been hacked.

The 18-year-old reality star's social media page was targeted by a user identifying themselves as @sw4ylol - a handle very similar to @lolsw4y, who hacked Katy Perry last year - who then unleashed a string of vulgar posts purporting to be from Kylie.

One post read: "I want ur c**k @justinbieber (sic)"

Another stated: "miss you both @taylorswift13 @katyperry.(sic)

And as well as a message saying Kylie "loves being famous with no talent", the hacker also referenced two controversies involving the teenager, including a rumoured sex tape with ex-boyfriend Tyga and an offer from a porn company to shoot an adult film.

One post read: "well my sex tape with tyga was trash (sic)"

And another said: "so when's the shoot? @pornhub (sic)"

However, Kylie insisted she "didn't care" about having her account violated.

She said in a Snapchat video: "So my Twitter was hacked, and I don't really care. I'm just letting him have fun."

And while she insisted fans will "never" see a sex tape from her, the 'Keeping Up With the Kardashians' star didn't deny if one exists.

She said: "Everyone's like, 'Leak the sex tape.' Guys, your never gonna see a sex tape from me. It's not going to happen."

Kylie's account now appears to be back under her control, as the offensive tweets have all been removed.

And the apparent hacker has had their own account on the social media site suspended.

The breach came less than a day after Tenacious D's Twitter page was hacked and a message posted which claimed Jack Black had died.

But the hacker later reassured upset fans they were the victims of a "prank".

They wrote: "Calm down guys! It's just a prank bro, look there's the camera...

"While you are all on Twitter, you should all follow me Ruthless XDDD"
