The lost son of the Kardashian family, Rob, was apparently not informed that his stepfather Caitlyn Jenner would be debuting her new look on the cover of Vanity Fair until after the fact. When Rob’s sister Kim sent him a photo of the cover, he replied, “Who is this woman?”

Oh, Rob. Kim explained the funny mix-up to Access Hollywood last night:

It was so funny because all the girls, we knew that Caitlyn was shooting this but my brother had no idea. So I sent it on a mass text to everyone and my brother was on it and he goes, “Kim, why are you sending me this? Who is this woman? And why do I care?” And I was like, “Rob, that’s Bruce! That’s Caitlyn!”

Rob then responded, “Oh my god, she’s beautiful!” according to Kim. “He called her and they had a lovefest and it was so cute. But the moment was so funny.”

I’m glad everything’s okay.
