Rob Kardashian is showing off his softer side. The 29-year-old star took to Instagram yesterday to post a touching tribute to his his fiancé Blac Chyna in honor of Mother's Day, and it looks like impending fatherhood has him feeling extra emotional. (ICYMI: The sole Kardashian brother and his lady love announced last week that they were expecting their first child together and broke the internet.)
"And last but not least happy mamas day to this beautiful Mama," he captioned a snap of himself and Chyna. "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 ! Thank You Chy for everything you do for me."
But Kardashian didn't stop there. He also gave a shout out to his own mother Kris Jenner on social media, along with his grandma Mary Jo Shannon and sisters Kourtney Kardashian and Kim Kardashian West.
While this will be Rob's first baby, it will the second for Chyna—she's already mom to 3-year-old King Cairo with rapper Tyga, and the model celebrated the holiday by sharing an adorable video of her and her little boy. Watch it below.
