Let's just call this yet another example of how Rob Kardashian has no patience whatsoever. The lone male Kardashian sister gifted his pregnant fiancee, Blac Chyna, with a bouquet of white roses for Mother's Day, Chyna revealed on her Instagram. And the dad-to-be gave her a tribute on his own Instagram account as well, so you know it's love.

"Happy mamas day to this beautiful Mama, I fell in Love with her immediately because of how great of a mom she is and now I'm looking forward to starting a Family with her," he wrote. "Thank You Chy for everything you do for me."

Kardashian's whirlwind romance with Chyna has seen dating, engagement and pregnancy announcements coming weeks apart from each other, and now he can't even wait until she's had the baby to celebrate her being a mom, which seems like it's against the rules of Mother's Day? Can't you just wait until next year? How silly of me, look who I'm asking.
