Kourtney Kardashian has made her first major change since tying the knot with Travis Barker over the weekend. 

The Poosh founder married the Blink-182 drummer in a lavish wedding in the picturesque village of Portofino, Italy on Sunday, after more than a year of dating. 

Celebrity guests included Kourtney’s mother, Kris Jenner, and sisters Kim, Khloe, Kylie and Kendall, while Travis was joined by his bandmates and his children, as well as best friends Machine Gun Kelly and Megan Fox. 

As the newlyweds recovered from their late night after partying until 3am at the wedding reception, Kourtney, 43, returned to Instagram to make one very important update. 

Fans will notice that her Instagram bio, which previously just said ‘Kourtney’, has now been changed to: ‘Kourtney Kardashian Barker,’ showing the reality star will be adding her husband’s last name to hers. 

The mother-of-three had previously hinted at the name change when she shared photos of her and Travis at the altar, with the caption: ‘Introducing Mr. And Mrs. Barker.’

It’s the first time down the aisle for Kourtney, while Travis, 46, has been married twice before; first briefly to Melissa Kennedy and then to actress and former Miss USA titleholder Shanna Moakler, with who he shares two children.

On Monday afternoon, Kourtney and Travis – or Kravis as they are affectionately dubbed – emerged from their newlywed slumber on their superyacht to go for a huge splash in the sea. 

They were pictured holding hands and standing on the edge of the deck before hurling themselves into the water, still dressed in their pyjamas.

Kourtney’s daughter Penelope, nine, and seven-year-old Reign, from her relationship with Scott Disick, were also spotted on the boat. 

The Kardashians star is also mother to Mason, 12, and all three of her children were in attendance for the ceremony.
