Bruce Jenner continues to fire up sex change rumors with his shocking physical transformation. Just recently, the 65-year-old former athlete was mocked by a bystander because of his appearance, Radar Online reports.

While driving his vehicle out of a parking lot in Los Angeles, California, Jenner reportedly received a verbal jab from an onlooker while paparazzi clicked their shutters on. According to Radar Online, the onlooker yelled, "Good job girl," as Jenner drove away from the place. The reality star appeared to not have heard the taunt, or probably pretended that he didn't.

As of late, the TV personality has been spotted sporting hot pink nails, sleek long hair, hairless legs, and was even wearing Spanx like her step-daughters Kourtney, Kim, and Khloe Kardashian. Daily Mail reports that he "seeking gender reassignment treatment with a preference to be named 'Brigitte,' and that his 'goal is to live as a woman and look as much like one'."

An insider also revealed that Jenner has long been struggling with his feelings about feeling a woman inside, Daily Mail notes.

Radar Online adds that he even had surgery to remove his Adam's apple, saying that he just didn't like his trachea. Another report from the gossip site states that Jenner does not aim to have a full gender reassignment surgery, but is only "taking the female hormone estrogen to further feminize his appearance."

Jenner's sons, Brandon and Brody, reportedly believe that their father is really on his way to becoming a woman -- at least on the outside. But Kris Jenner, the former athlete's ex-wife, said that the rumors aren't true.

"That's a story they've been saying since the 70s and I think they just keep regurgitating stuff. The more sensational the headline, they are going to sell more magazines," she said, Radar Online reports.

However, the gossip site's insider insisted that Jenner's sons are supportive of him. "Brody and Brandon love their dad, and if Bruce did finally admit that he was transitioning and becoming a woman, it wouldn't change how they felt about him. They are both very open supporters of the LGBT community," Radar Online's source revealed.

Despite the criticisms and ridicule coming his way, Jenner seems to be happy with his striking physical transformation. "I'm finally free to do what I want and live life the way I want," he said during an event, as quoted by Radar Online. An insider also revealed to Daily Mail that Jenner plans to unveil his gender identification in the format of his own choosing, preferably in an in-depth interview, Oprah-style.
