Bruce Jenner's dramatic look changes have once again sparked sex change rumours.

On 4 October, he was spotted with long shiny hair while attending Elton John's concert at Staples Center in Los Angeles.

The 64-year-old former Olympic star, who was joined by son Brandon Jenner and his wife Leah at the event, looked feminine with voluminous brown locks.

The Keeping Up With The Kardashians star's fans took to Twitter to express their disbelief.

I love Bruce Jenner but he needs a damn haircut. He's looking like a woman. Definitely not a good looking woman. 😱😟

Bruce Jenner was spotted with even longer locks, further fueling sex change rumors. Makes sense considering Kris removed his balls years ago

In February, Bruce checked into Beverly Hills Surgical Center for a 'laryngeal shave,' a surgery to reduce the appearance of the Adam's apple, sparking rumours about him getting a sex change. He was photographed leaving the office with bandages around his neck.

Last October, Kris and Bruce Jenner announced they were separating after 22 years of marriage. Star magazine claimed they split because of his sexuality.

However, Kris spoke out about the rumours surrounding her estranged husband.

"Ninety-nine percent of the stuff in the tabloids is made up," Kris told Entertainment Tonight in an interview.

It was previously reported that his daughters, Kendall Jenner, and Kylie Jenner are very upset over him changing his physical appearance.
