Kylie Jenner is reportedly upset over father Bruce's alleged transition into a woman; how is her rumored boyfriend Tyga helping her?

Us Weekly recently reported that Bruce, who was spotted out in public wearing a bra and Spanx, had already started getting plastic surgery and began his sex change when he met his wife Kris in the early '90s. However, his then-girlfriend talked him out of it, and he put it on hold.

Now that he is divorced, the former Olympian is apparently continuing with the transition: he had the Adam's apple surgery, started taking the female hormone pills, removed his leg hair, grew his hair long and began painting his nails.

Moreover, TMZ confirmed that E! has been filming a docu-series about Bruce's "journey" over the last few months, stating, "The footage is a very personal look from Bruce's vantage point of the process of changing. Multiple sources say the documentary will include interaction with Bruce's kids and ex-wife Kris and how they are receiving the news."

With that being said, the "Ayo" rapper has reportedly been comforting the 17-year-old reality star to better deal with such sensitive matter. "At this stage, Tyga's not trying to press that situation or even talk to her about what her dad is going through," a source revealed to HollywoodLife.com. "He's very close to the family and obviously to Kylie but he doesn't want to aggravate the situation. He knows it's something that's stressing her out."

The source added that Tyga has been keeping Kylie busy and letting her to lean on him: "He knows Bruce's situation is weighing on everybody in the family, especially Kylie. He's trying to make her feel better by making her laugh and listening to music."

Kylie is not the only who is reportedly unhappy about Bruce's sex change.

"[Kris] immediately wants to get back home and sit everyone down and figure out what the hell is going on. She's preparing a family intervention and she means business!" another source told HollywoodLife.com. "Paris was supposed to be fun, but it's turned into Kris' worst nightmare because of all the drama back home and she's not there to control it."
