Kylie Jenner's Birthday Cake for Travis Scott Is Freaking People Out

The whole Kardashian-Jenner crew is known for their tradition of celebrating occasions with outrageous cakes: Most recently, Kourtney Kardashian feted 40 with a NSFW cake topped with a nude selfie. For her part, Kylie Jenner celebrated her 21st with a birthday cake topped with a bafring Barbie doll. And when her daughter, Stormi, turned one earlier this year, Kylie went all out with an extravagant, motorized confection that took the form of a moving circus carousel.

Well, now Stormi's dad and Kylie's beau Travis Scott is celebrating a birthday of his own — so Kylie naturally called in a major cake to celebrate. But it's not so much the cake's over-the-top design this time that's raising eyebrows around the Internet....

For his 28th birthday, the family celebrated with an Avengers-theme party, dressing in corresponding costumes. The cake — like Kylie's birthday cake for Travis last year — featured miniature figures of the fam. This time, they appeared as super hero characters: Iron Man, Captain Marvel, and Thor, just as they'd dressed for the party:

But how about the message emblazoned on the cake's plaque backdrop? Well, that's what's lighting up Instagram right now after family members like Khloe and Kim shared the pic. It reads: "Happy birthday, husband!"

It's far from the first time Kylie and Travis have referred to each other as spouses — in fact, they regularly play the marriage-trolling game on social media — although if they are actually already married, the public doesn't yet officially know.
