Reality star Kendall Jenner has denied making a statement about her father Bruce Jenner's alleged sex change during a candid interview with Us Weekly.

The magazine had reported that the 19-year-old model had broke her silence backstage at Comedy Central's roast of Justin Bieber, vowing to support the former Olympian.

She is quoted to have said: "I will always love my dad, whether he's a man or a woman. I love my dad. He's always been there for me and my sisters.

"He's a wonderful man. And just because he's changing shoes now, so to speak, doesn't make him less wonderful," she allegedly added.

Taking to Twitter, Jenner slammed the suggestion she had made a statement about her father transitioning into a woman.

Half-sister Khloe Kardashian co-signed her denial by retweeting the message to her army of twitter followers.

Bruce has been the focus of sex-change rumours after he reportedly had his Adam's apple surgically reduced, a common procedure by men seeking gender reassignment. He also allegedly started taking oestrogen and asked to be referred to as "Brigitte".

People Magazine recently claimed that the 65-year-old's stepdaughters struggled to come to terms with his decision and that he is no longer on speaking terms with ex-wife Kris.

"They were just hysterical when it all really came out," a source said of Kim, Kourtney and Khloe, who were the last to find out Bruce was making the change.

The insider added: "The divorce caused a divide, but Bruce's decision to share his transition has caused an even greater divide."

The article claims that while Bruce became aware in his early teens of his desire to dress as a woman, he spent almost 50 years in denial.

His announcement will be featured in episode 13 of Keeping Up With The Kardashians which airs on 15 March. It has been revealed that he is leaving the Keeping up with the Kardashians franchise to launch his own sin-off series for the E! Network, documenting his reported gender transition.
