Kylie Jenner has no chill when it comes to Travis Scott‘s birthday.

Celebrating her baby daddy’s 28th year, the reality star bought a billboard in Los Angeles.

“HAPPY BIRTHDAY DADDY” the massive sign read, and was signed, “LOVE, MOMMY AND STORMI XO”

The billboard, which made the rounds on the Internet on Saturday, was complete with an adorable black and white photo of baby Stormi and another image of her and Jenner together.

The huge gesture was just another part of his birthday celebrations.

The “Sicko Mode” rapper had an “Avengers: Endgame”-themed bash this week with the Kardashian/Jenner crew, where they were treated to an early screening of the highly anticipated movie.

Taking the theme very seriously, the 21-year-old beauty mogul took to Instagram on Friday with snaps of the couple dressed as Iron Man and Captain Marvel.

“Happy end game everyone,” she wrote of the two of them in their costumes while holding Stormi, who was born last year.

The party was complete with a matching cake — that read “Happy Birthday Husband” — and tons of sweets.

The two have not confirmed whether they are married, but often refer to each other as “wifey” and “hubby.”
