According to a new report, the Keeping Up With The Kardashians couple didn't get to see what Caitlyn Jenner looked like until her photos were released on Monday.

“Most of the family saw Caitlyn for the first time on the cover of Vanity Fair!” a source told Radar Online on Tuesday. “That is the way that she wanted it to be. In doing so, it gives them all a little more time for it to sink in.”

“Scott still intends of keeping the kids away from her until they are all able to fully wrap their mind around this,” the source alleged.
