New York, Nov 11 (ANI): Kim Kardashian has denied rumours that she had got butt implants done, saying that it was her tight Spandex-y pants that started the entire buzz.

The 27-year old model said that it was her gym snap in the tight leggings, which sparked the butt implants' rumours.

"There was that gym picture of me in the tight leggings, walking out with no makeup on. I had tight Spandex-y pants on - I think that is the picture that started the 'Oh my god I think she has butt implants' rumour," the New York Post quoted her, as saying.

"I mean, do you ever know anyone who has butt implants? Do people really do that? "It's, like, ridiculous. If they could see the cellulite, they'd know," she added.

Meanwhile Kardashian's infamous sex tape with her then boyfriend Jay Z, which came out in February, is now being released completely.

Vivid Entertainment is releasing 'Kim Kardashian Superstar Part two' on the net, which promises to have 1 hour of 'never-before seen sex'. (ANI)
