In the snapshot, Kardashian is seen posing in an elevator mirror while dressed in a white logo T-shirt, black pants, a long black coat and black chunky boots. The Kardashians star, who appeared to be fresh-faced, also wore her hair up and with a pair of black sunglasses on her head.

Kardashian simply captioned the photo with a black heart emoji.

On Saturday, Kardashian gave her fans a behind-the-scenes look at the party on her lifestyle website Poosh and revealed the bash was organized in just 48 hours with an "on-the-nose, rock-n-roll theme (plus a little of Kourt’s elevated, chic aesthetic)."

The couple announced their little one’s sex with a drum roll reveal and shared a video of the sweet moment on their respective Instagram accounts. The clip was simply captioned, “🩵or🩷.”

In the video, Kardashian sat on her 47-year-old husband’s lap at a drumkit on a stage. Barker then began a drumroll while kissing his wife, before hitting the drum's symbols just as a burst of blue streamers shot into the air above them.

They later revealed that they had already picked out a name for their son as they shared a series of pictures taken on the day of their sex reveal party on Instagram last week.

"I already know his name 😉,” the Blink-182 drummer teased in the comments section of the post, with the comment garnering nearly 10,000 likes.

In the maternity photos, Kardashian stunned in a light blue split-thigh dress paired with a matching set of mesh pants as they posed by a pool, while Barker kept it simple in a white muscle tank top, black jeans and a black beanie hat.
