Travis Scott Calls Kylie His Wife Day Before Mayor Declares 'Astroworld Day'

2:33 PM PT -- The Mayor of Houston, Sylvester Turner, just declared November 18 as "Astroworld Day" in an official proclamation to honor Travis and what he contributes to the city's arts, community, and in celebration of his latest album.

Mayor Turner held a ceremony Sunday at City Hall to make the announcement, and Trav himself took to the podium to reminisce on the real Astroworld, and to thank his hometown while encouraging it to embrace the arts as a foundational pillar for the youth.

Needless to say, Astroworld Fest was a success.

Travis Scott is at the top of his game, kinda like Justin Bieber. Is he also secretly married, like Justin Bieber?

Travis gave a shout out to Kylie Jenner in Houston Saturday night during his Astroworld Fest concert, and he referred to her as "my beautiful wife." That doesn't necessarily mean they're hitched, but then again it doesn't mean they're not.

Kylie and 9-month-old Stormi joined thousands at the Astroworld Amusement Park for Travis' set.

Check out the crowd ... far as the eye can see.

Kylie also posted pictures of Travis and Stormi on Instagram Saturday night with the caption, "only the people around you really know how hard you work. i love to watch you make all your dreams come true."

He commented back, "I love u wifey."
