Last night we reported that Kendall Jenner had broken her family's silence to a US magazine about Bruce Jenner's decision to transition to life as a woman.

Gossip magazine Us Weekly published quotes online which they claimed Kendall had made to their reporter backstage at a Comedy Central event over the weekend.

According to the magazine, Kendall said of her father: "He's a wonderful man. And just because he's changing shoes now, so to speak, doesn't make him less wonderful. I will always love my dad, whether he's a man or a woman."

Now though, the 19-year-old has hit back at Us Weekly, claiming she not only never said those things but that she never spoke to their reporter at all.

Kendall took to Twitter late last night, first posting a more cryptic tweet which read, "how is it legal for someone to "quote" someone and publish it if in fact you never said what was quoted."

Two hours later she followed up with another tweet, this time mentioning the magazine by name and writing, "Shame on US Weekly for making up quotes. I NEVER said those things. I never spoke to them."

The story in question still appears on Us Weekly's site, and as well as the Bruce quotes it also features comments, supposedly from Kendall, about the rest of her family, her modelling career and growing up in the public eye.

Kendall Jenner has become the first Kardashian-Jenner sister to speak openly about their dad Bruce's decision to transition to life as a woman.

Her older sister Kim Kardashian did allude to Bruce's sex change in an interview earlier this year, saying that the family "support Bruce one hundred per cent."

However Kendall has finally spoken openly about Bruce's decision and what it means for her family.

Speaking backstage at Comedy Central's Justin Bieber roast over the weekend, the 19-year-old told Us Weekly that she will support her father no matter what.

"He's a wonderful man. And just because he's changing shoes now, so to speak, doesn't make him less wonderful. I will always love my dad, whether he's a man or a woman," she said.

Kendall said she will stand by her dad as he did for her and her siblings. "I love my dad. He's always been there for me and my sisters," she said.

Although no other family members except for Bruce's mother Esther have openly spoken about Bruce's sex change, sources have said the whole clan have rallied around him.

Bruce has six children and four stepchildren with his ex-wives Kris Jenner, Linda Thompson and Chrystie Crownover. Among them are Kendall, Kylie, Kim, Khloé and Kourtney – five of the family's most high profile members.

Speaking about the close bond she shares with her sisters, Kendall said the girls are always very supportive of one another. "We are all very tight, and we tell each other everything," she said. "I am so proud of all of them. I spend as much time with them as I possibly can."
