A sex tape purportedly featuring WWE superstars Lana and Rusev is not the real thing, sources close to the popular wrestling couple have claimed.

Lana, real name Catherine Joy Perry, appeared to have had her Snapchat account hacked on Thursday, when an x-rated homemade clip was posted to her account - reportedly sparking an investigation by the WWE.

According to The Sun, the clip was taken down soon after.

The 34-year-old wrestler, who has more than a million followers, appeared to confirm that she had been hacked with a post on Twitter.

A source close to the 34-year-old, known as the Ravishing Russian, told TMZ Sports the female in the amateur clip "is clearly not Lana". Respected website Ringside News also reported it is not Lana or Rusev in the clip.

It is not the first time Lana has been hacked after her Instagram account was targeted last October, according to The Sun.

Several other high-profile female WWE stars have been victims of leaked sex tapes and nude pictures in the past year, including New Zealand-born Toni Storm and the recently retired Paige.

Storm was forced to delete her social media accounts in January after hacked naked pictures of her were leaked online.

Paige was the victim of hackers in 2017 and revealed how her sex tape leak left her suicidal.
