Bruce Jenner's sons have reportedly come to terms with their father's alleged intention to become a woman. But his daughters – Kylie and Kendall – are a bit confused by their father's physical transformation.

Also, friends of the teens have been unsympathetic and they often crack jokes on Bruce's feminised appearance, making it difficult for Kylie and Kendall to accept Bruce's changes, reports said.

"Kylie and Kendall just don't know what to think. It's extremely confusing for them to grasp. There is just no denying Bruce's recent physical changes, and he does look more feminine," a source told Radar Online.

While Bruce's estranged wife Kris said that the sex change story was cooked up by the media and that there was no truth to it, Bruce was recently seen out and about in Los Angeles after his alleged laryngeal shave to minimise the appearance of his Adam's apple.

A laryngeal shave is generally part of gender reassignment procedure.

He was also sporting an ombré hair do similar to that of his daughters.

"It's been especially hard for 16-year-old Kylie because some of her friends have made jokes about Bruce's looks. The ridicule aimed at Bruce's looks on social media has also taken a toll on Kendall and Kylie."

The source added that while Kendall has been spending more time with her father, Kylie has been hanging out with Bruce only for filming of "Keeping Up With the Kardashians".

Meanwhile, another report claims that despite Bruce's intention to become a woman, he will not undergo a sex change as he does not want to embarrass his daughters.

"As much as he wants to become a woman he will only do a select amount of things" for the sake of his daughters, a source told HollywoodLife.com.

"[Bruce] knows the drama it will cause will be monumental, and doesn't want that media storm even though he'd be more comfortable as a woman," the source added.
