Kourtney Kardashian has officially changed her name. On Instagram, The Kardashians star posted a photo of her driver's license showing her new name. It's been more than a year since she married Travis Barker, but she can now officially say she is Kourtney Kardashian Barker, per People.

“Say my name,” Kardashian wrote in the caption of the photo, which featured a black and white headshot of her driver's license and her full married name written out underneath.

As for why she kept the name Kardashian, she shared a photo of a website called the Knot, writing “In case you didn’t know…” over top of the text which read: “It’s long been tradition for the bride to take the husband’s last name, and traditionally, she drops her middle name and keeps her last (her “maiden” name) as her middle name. Her husband’s last name then becomes her new last name.”
