After wishing his mom, Kris Jenner, grandmother and sisters Kim and Kourtney Kardashian a Happy Mother's Day on Instagram, he posted a sweet message to his fiancée.
“And last but not least happy mamas day to this beautiful Mama,” he captioned a snapshot of the two of them. “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.”
The formerly reclusive reality star, 29, included a bride emoji with his caption (the pair announced their engagement at the beginning of April).
The pair shared their baby news via Instagram on Friday, May 6. A rep for the 27-year-old makeup artist confirmed the news to Us, saying that “she’s very happy.”
Earlier on Sunday, Rob shared a throwback photo of himself with his mom, Kris, and noted that he was “appreciating all the moms heavy today.”
“Once again mama I love you and thanks for putting up with your 6 crazy kids every single day and love you more than you know,”
Rob spent Mother’s Day with his family; his older sister Kourtney shared a Snapchat of a beautiful bouquet that he gifted her with a note: “Happy Mother’s Day. You are a beautiful momma. Love, Rob.”
The expectant mom played with different Snapchat filters as she and her 3-year-old son goofed off for the camera. She also posted Snapchat videos of the beautiful flowers that Rob gave her, along with a collection of designer bags.
