Kylie Jenner is "breaking Bruce's heart."
The 'Keeping Up With The Kardashians' star is said to be avoiding her father at all costs and "shutting him out" over his rumoured gender transition.
A source said: "[She] keeps promising to visit Bruce at his Malibu mansion, but she never shows. And most of the time, Kylie doesn't even have the courtesy to call Bruce to say she isn't coming!
"Obviously it has to be very hard for a teenager to have a father go through a sex change, and it seems she is embarrassed.
"But Kylie is just shutting Bruce out and it's breaking his heart. Offering to go to counselling with Kylie hasn't helped. He has no other choice but to let Kylie do her own thing, and hope she will eventually come around."
Bruce's ex-wife Kris was previously seen visiting the 65-year-old Olympian's home but an insider has claimed it was just a "public relations stunt".
They added: "It was all a public relations stunt. Kris wanted to be photographed arriving at the house. Feeling backlash from the public, Kris felt it was important to at least make it look as if she was being supportive."
And Bruce's older daughter Kendall has been showing her support to her father despite being busy travelling.
The source told RadarOnline.com: "She has been video chatting with Bruce ... She knows it's important for Bruce.
"Kendall is extremely empathetic and has a very, very kind heart."
