Bruce Jenner's step-daughters reportedly "hysterical" upon news he was allegedly transitioning into a woman

A source told People magazine of the sisters: "They were just hysterical when it all really came out.

"The divorce caused a divide, but Bruce's decision to share his transition has caused an even greater divide."

The 65-year-old reality TV star sparked rumours he was keen to become a woman after he grew his hair longer, had his Adam's apple made smaller, and started wearing nail varnish.

The insider added: "Everyone thought he was trying to feel young, that kind of thing. The whole family went through a rough patch. It's naturally a difficult thing to process and work through."

Meanwhile, Bruce's daughter Kendall, 19 - his eldest child with Kris - recently opened up about her father's change and admitted she will love him regardless of whether he's a man or a woman.

She said earlier this week: "I love my dad. He's always been there for me and my sisters.

"He's a wonderful man. And just because he's changing shoes now, so to speak, doesn't make him less wonderful. I will always love my dad, whether he's a man or a woman."

Bruce also has 17-year-old daughter Kylie with the matriarch, as well as two grown-up children Burt and Casey from his first marriage to Chrystie Crownover, and sons Brandon, 33, and Brody, 31, with his second spouse Linda Thompson.
