Kourtney Kardashian and Travis Barker discovered the sex of their unborn child at a lavish party over the weekend, with fans given an insight into the occasion on social media.
The reality TV star, 44, announced just over a week ago that she's expecting a baby with her husband, 47, whom she has been married to since their wedding in Italy last year.
She shared the news whilst supporting the musician - who's a member of band Blink-182 - at a concert in Los Angeles, where she held up a sign that read: "Travis I'm pregnant".
More recently, they gathered with family and friends at a venue in Calabasas, California, on Saturday to announce the sex of their unborn child, who is due in the coming months.
It appears that the event was themed around a concert tour, with guests given lanyards that read: "Baby Barker world tour with special guests Kravis. All Access."
A poster greeted attendees at the entrance which featured the same artwork and teased a performance by Kourtney and Travis, known collectively as Kravis.
The couple were seen sat at a drum kit for the reveal itself, with drummer Travis playing the instrument for a moment before blue confetti came down over the gathering.
It seemingly announced that the couple are expecting a son together, which Kourtney teased that she had predicted through her choice of outfit for the party on Saturday.
Alongside other content from the event that she shared on Instagram, the reality TV star showcased her blue outfit and wrote in the caption: "Baby blue (mommy's instinct?)".
She gave her followers on the platform an insight into the party in other posts, including sharing a photo of a menu that showcased the food that was available to guests.
Those in attendance were treated to a variety of food at the party, with the menu showing that it included beef and vegan sliders, hot dogs, sweet potato fries and nachos.
Kourtney also shared a photo of some cookies that were seemingly available at the gathering, which had been decorated with music notes, microphones and other designs.
And there was also a cake that had been adorned with cream icing and black hearts on the top. Kourtney later showed off the inside of the cake, which was blue and white.
Organisers had also decorated the property where the party was held over the weekend, including putting up black balloons, drum kits and floral arrangements on some tables.
Other aspects teased by Kourtney include that guests were invited to save "tour memories" by using a disposable camera and then leave a note to go along with the photos.
Kourtney's video of the reveal itself has amassed more than 2 million likes on the platform and prompted supportive messages from some followers in the comments section.
