Find Out How The Kardashian And Jenner Family Reacted When Bruce Jenner Told Them He’s Transitioning Into A Woman

“Bruce told them everything – where things stood, what his plans were for the future, and what everyone could expect," a source told People.

As for the rest of the family, they all stand by their father. “They all came all around pretty quickly, but each of them had to process it in their own way," the source told the magazine. "All they want is for him to be happy."

But there is one member of the family that the brood is having a hard time breaking the news to: Mason. A source told RadarOnline.com of Kourtney and Scott’s 5-year-old son, “As of right now, Bruce is ‘Pop-Pop’ to Mason and they do not know how they are going to tell Mason Bruce is going to now be a grandma.” The source added, “Penelope is at that age where she will not remember Bruce as a man… and the same thing with Reign. But Mason is so inquisitive and nothing gets by him.”

Bruce has made headlines ever since his split from Kris last year for his ever-changing appearance. Reported lip injections and a shaved Adam’s Apple, pierced ears and manicures have only fueled the rumors. He is even reportedly set to have an E! reality show of his own about the transition, as well as a sit-down interview with Diane Sawyer.
