Bruce Jenner Will Reportedly Address Changing Appearance In Upcoming 'Keeping Up With The Kardashians'

Bruce Jenner Spends Quality Time With His Daughters In Kim Kardashian's Instagram Post

The Keeping Up With The Kardashian star wore the baseball cap with his casual look. He wore a double-layered T-shirt over tracksuit pants and animal-print slippers.

Over the past few months, speculation has increased that Jenner underwent a sex change operation, and a change in his appearance has increased the questioning.

In the last few weeks, Jenner has apparently been seen with different hairstyles and even French manicures.

It's rumored that he recently returned from Thailand which is where people think he had the operation.

According to InTouch Weekly, the 65-year-old reportedly agreed to film it for Keeping Up With The Kardashians, so fans of the show will know the truth.

The timing is certainly interesting, as the site points out that he underwent plastic surgery this time last year to shave down his trachea. It's also noted that this type of operation is typically performed on patients in the early stages of gender reassignment.

Also amid Jenner's sex change operation, it's reported that his friends say he has become "much prissier" lately and that his golf game is suffering.
