The 'Keeping Up With The Kardashians' star, Bruce Jenner, has undergone several physical transformations, including growing out his hair, which invited rumors about his sexual identity. However, his family denied the allegations, defending Jenner's masculinity.

Sex change rumors involving Jenner have escalated after he appeared with long hair at an Elton John concert at the Staples Center.

Jenner, 64, has been growing out his hair ever since his divorce with co-star Kris Kardashian on October 2013. His hair has already grown past his shoulders, which made fans wonder if the former athlete is planning a sex change in the near future.

Additionally, Jenner was allegedly spotted with his legs suspiciously smooth and nails painted hot pink.

The speculations about his sexual orientation started after the actor reported his Adam's apple being surgically removed, one of the first procedures in gender reassignment surgery. Jenner, however, denied the rumors, stating that he underwent the procedure because he "just didn't like his trachea."

There were also reports that Jenner was asking advice from Dr. Renee Richards about gender reassignment surgery, according to Hollywood Take. For those that may not know, Dr. Richards transitioned into a woman back in 1975.

However, Kardashians and Jenners have consistently refuted the allegations. In an interview on Australia's 'Kyle and Jackie O' radio show, Bruce Jenner's ex-wife denied the rumors, according to International Business Times.

"That's a story they've been writing since the '70s," Kris Kardashian said, "I think they just keep regurgitating stuff.. and the more sensational the headline, they are going to sell magazines." She continued and shared her unbelief that "these blatant lies are printed" and that "people are gullible" and are buying the magazines.

On the contrary, Mr. Jenner's daughter Cassandra Marino expressed her support to her father's decisions. She said that nobody knows how it is to be in his father's skin. She continued by saying, "if that's what he chooses to do, then I support him."

Bruce Jenner and Kris Kardashian have been married for 23 years with two daughters, Kendall and Kylie. On the other hand, Cassandra Marino, also known as Casey Jenner, is Mr. Jenner's eldest daughter with Chrystie Crownover.
