Kourtney Kardashian has officially changed her last name - and ditched her middle name.
The 44-year-old took to Instagram to announce that she had made 'Kardashian' her middle name and added 'Barker' as her new surname.
The reality star's full name was previously Kourtney Mary Kardashian and she will now be known as Kourtney Kardashian Barker instead.
She shared a snap of her new drivers license picture, adding the caption: "Say my name."
Kourtney provided more clarity about her decision to go by Kourtney Kardashian Barker in her Instagram Story, where she uploaded a quote which read: "It's long been tradition for the bride to take her husband's last name.
"Traditionally, she drops her middle name and keep her last name (her "maiden" name") as her middle name. Her husband's last name becomes her new last name."
She then added: "In case you didn't know."
It comes after Kourtney and Travis announced that they were expecting their first child together. At a Blink-182 concert, she held up a sign in the crowd which read: "Travis I'm pregnant," in a remake of one of the punk rockers' most memorable song videos.
Shortly after, they had a lavish gender reveal, with Travis playing the drums outside in a build-up to blue smoke and ribbons flying into the sky.
He then passionately kissed his reality TV star wife as the pair celebrated finding out they were having a little boy.
And now, as the couple continue to bask in the glow of their announcement, Travis has teased fans that the child already has a name.
As the POOSH founder posted a number of maternity portraits to her social media, she told her followers: "Little drummer boy coming soon."
She looked stunning in the upload as she wore an airy lilac gown with a black belt around her midriff. She stood in front of a beautiful looking swimming pool while the sun beamed down.
Travis decided to drop a message in the comments section to further tease the pair's fans ahead of the birth, writing: "I already know his name."
He ended his post with a winking face emoji.
