The reality star took to Instagram on Tuesday to wish her longtime love, Travis Scott, a happy 28th birthday with a sweet (but also hilarious) tribute.
"Watching you evolve into the partner, friend, son and father you are today has been so fulfilling," wrote Kylie, who shares 1-year-old daughter Stormi with Travis. "My real life bestie & hubby all wrapped into one."
"I love you and I'm so so proud of you," she added. "Happy happy birthday ?? Let's f**k around and have another baby."
The posts come just a few days after Kylie and Travis' closest family and friends gathered together to celebrate the rapper's special day with an Avengers: Endgame-themed birthday bash.

The beauty mogul continued to go above and beyond for Travis' 28th, renting out a billboard in Los Angeles that featured a giant close-up shot of Stormi and the words, "Happy Birthday Daddy!"
It seems that Kylie is now ready to give her daughter a baby brother or sister, despite recently telling Germany's Interview magazine that she did "not have any plans in the near future to have children right now."
"I always knew I wanted to be a young mother," she said. "I remember people used to ask, 'Are you ready for this?' And I always knew I was ready but you don't know what that love and that feeling is like until after you have a child."
"[Stormi] really comes before me, so that is a lot to take in at a young age, but I feel like I was definitely made for this and she has changed my life for the better," the reality star added. "The way that I look at things is a lot more positive and I really feel like my life didn't start until I had her."
