Rob Kardashian is wishing "pretty mama" Blac Chyna a happy birthday.
The 30-year-old reality star took to Instagram on Thursday to send his on-again, off-again fiancee his best wishes after skipping out on her birthday party the night before.
"Happy birthday @blacchyna 🍉🍉," Kardashian wrote alongside a throwback photo of himself and Chyna at Legoland, captioning another pic, "Happy birthday pretty mama @blacchyna."
"I've always felt like them as a couple is just not that healthy, and I think they know it too," she said. "It's not just like some secret."
