It looks as though not everyone is on board with Bruce Jenner's rumored "transformation." According to a new report, 17-year-old Kylie Jenner is rumored to be "stressing out" about her father's changing appearance these days while he is supposedly transitioning into a woman.

Hollywood Life reports on Friday that Kylie has been leaning on her rumored boyfriend Tyga for support during this difficult time in her life.

A source told the site that the rapper knows how to deal with this "sensitive issue" as he is trying to help her out while her father is going through some major changes in his life, following his split from ex-wife Kris Jenner.

The insider said, "At this stage, Tyga's not trying to press that situation or even talk to her about what her dad is going through. 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, "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."

What's more, it doesn't look like Bruce's plans to become a woman is surprising to his family, as they've known about it for years.

"Bruce has had these urges for many year, so the kids have known," Us Weekly reported on Jan. 29. "Brody [Jenner] talks to Bruce every day and tells him that he loves him. They all have become protective of him and just want him to live the way he wants."

So far, Kylie hasn't made any public comments about Bruce to the media.
