The Kardashians had some VERY mixed reactions to Bruce’s decision

Although Bruce Jenner has yet to speak out himself about his decision to transition to life as a woman, other family members including his mother have confirmed the news.

While his step-daughter Kim Kardashian said in a recent interview with Entertainment Tonight that Bruce has the family's support, and that they will stand by him "100 percent," it seems it took some of the others a little longer to come to terms with.

"Bruce told them everything – where things stood, what his plans were for the future, and what everyone could expect," a family insider revealed to PEOPLE magazine.

"Everyone basically knew what was up, but it was still a shock to hear it outlined so explicitly." 

While it took the sisters some time to get used to the idea, their main concern was the welfare of their mum Kris Jenner. "Kim went to Kris and asked her how she felt. They had a very long conversation about it," says the insider. "Once Kim was satisfied that Kris was emotionally okay, she was able to give Bruce her unconditional support." 

Even though the girls of the family came around quite fast, Kourtney's boyfriend Scott didn't find Bruce's decision quite so easy to come to terms with. The father of Kourtney's three children "didn't react very well" at first, but "is now on board," according to the source.

As for Kim's husband Kanye, he reportedly "took it all in his stride" and is "totally fine" with Bruce's choice.

We're delighted to hear the Kardashian-Jenner(-Disick-West) clan are doing all they can to support Bruce at this time!
