Rumors about Bruce Jenner's desire for a sex change have once again made headlines as the former Olympian and 'Keeping Up With The Kardashians' star was recently spotting looking rather strange.

Apparently, Bruce Jenner was seen with his hair in a ponytail, and his chest seemingly enlarged via an alleged estrogen treatment.

Gossip about a possible sex change operation has been swarming the former U.S. track and field athlete, but all rumors have been denied.

His wife, Kris Jenner, has personally denied the allegations as intrigues about Jenner's sexuality continue to arise, especially since gradual changes in his physical appearance have been noticed by the public.

With his recent look, sources suspect that Jenner is undergoing estrogen treatment, which is another procedure that's precursor to sex change operations.

Early this year, the Olympic gold medalist made headlines when he underwent a laryngeal shave, which is a procedure that flattens the Adam's apple.

Even though a laryngeal shave is something commonly done before a sex change operation, Jenner told TMZ that a sex change wasn't the reason behind the surgery.

"I just never liked my trachea," said Jenner.

Despite stating his reason for the procedure, rumors of his alleged desire to become a woman did not cease. Reports even claimed that Jenner wants to be called "Brigitte" after his sex change.

"At first Bruce was intrigued with Bruscilla, but after he thought about it some more, he decided it didn't work for him," a source said, "He loves 'Brigitte' not only because it's such a beautiful name, but it makes him think of Brigitte Bardot, who was a total bombshell."

Kris Jenner came to Bruce's defense, and had denied all the rumors flat out.

"Ninety-nine percent of the stuff in the tabloids is made up. I think when he gets his nails buffed they put clear [nail polish on him]. The bottom line is, we sell magazines," the Kardashian matriarch told Entertainment Tonight.
