Kris Jenner Breaks Silence On Speculation Bruce Jenner Is Becoming A Woman 'It's Just Dumb'

An insider revealed to Us Weekly that there is meaning behind a family snapshot Khloe Kardashian shared on Instagram back in January. In the picture all of the girls (Kim, Khloe and Kourtney Kardashian) surround Bruce Jenner with his youngest two, Kylie & Kendall Jenner embracing him. Khloe captioned the picture, "Family"

The source said Jenner had just told the girls about his decision and the picture was Khloe's way of showing her support.

He went on to request that they drop the name Bruce and begin to call him a new name, which hasn't been revealed yet.

They continued and said he was "a little emotional" but made it clear that "it wasn't a jaw-dropping conversation."

What he didn't tell him is whether he will get surgery to make it official, something his daughters reportedly don't care to know.

"That is such an elephant in the room. But the girls are good with elephants."

Word is that cameras were there and Jenner's big reveal will air on the upcoming season E!'s Keeping Up With The Kardashians. There have also been reports that he will have his own docu-series to share his journey.

But for starters he reportedly will "wear women's clothes more around the house and will gradually make little changes in a more public manner. He feels so much better to be in control of his body."

He recently split from Kris Jenner after being married for nearly 25 years.
