She officially tied the knot with Travis Barker with a small courthouse wedding in San Diego over the weekend.
The exciting union has left Kourtney Kardashian's fans questioning whether she will change her famous surname to the Blink-182 drummer's .
And some eagle-eyed followers believe they've uncovered a major hint that has given away exactly how Kourtney's plans to name herself following her wedding.
Taking to her Instagram account, the mum-of-three recently shared a short clip of her opening up a box filled with a celebratory heart-shaped cookie that read "Mr + Mrs Barker" in dark red icing.
The post sent tongues wagging as a number of fans began to theorise that the decorated cookie was a huge hint in regards to what she will possibly be changing her name to.
One particular Reddit forum, r/KUWTK, was awash with speculation as many fans concluded that Kourtney will be exchanging her family's moniker to that of her husband's thanks to the telling social media clip.
One said: "She actually might [change her name]. Girl is reckless! Lol," as No_Band_5659 agreed: "Yeah she seems all in lol."
While another theorised: "I think she’ll do a hyphenated version. Kardashian-Barker or vice versa."
A third echoed: "I think Kourtney loves her dad too much to ‘give up’ his last name. I see her as forever wanting to honour home. I bet she’ll hyphenate."
"I think she’ll follow the same format Kim did when she was a West." a different fan added.
Another follower said: "Plot twist, Travis Kardashian. Because it’s totally ‘new-Skool’ and edgy, plus then his initials would be their first name initials and think of the romance. Sarcasm is totally intended."
The loved-up couple got married in a low-key ceremony in Santa Barbara, California, after their 'practice wedding' in Los Vegas in April.
The reality star shared a photo with her 177 million followers on Monday showing her and her new husband seated in a black convertible kissing with “Just married” and cans tied to the rear bumper.
Kardashian’s accompanying caption said: “Till death do us part.”
Barker shared an identical post to his 6.9 million followers with the same image and caption.
The couple had earlier held a “practice” wedding after the Grammys in April hosted by an Elvis impersonator at 2am.
They became engaged in October 2021.
