The band, set to perform in Scotland on Friday and Saturday, announced on Instagram that Barker had to return home to the United States
The band shared the news on their Instagram account Friday morning, writing in a Story, "Due to an urgent family matter, Travis has had to return home to the States. The Glasgow, Belfast, and Dublin shows are being postponed. More information in regards to his return to Europe and rescheduled dates will be provided as soon as available."
It’s not clear what Barker, 47, has had to return home for. PEOPLE has reached out for comment.
The "All the Small Things" rockers were due to take to the stage at the OVO Hydro in Glasgow, Scotland on Friday and Saturday, before traveling to Belfast and Dublin for further stops on their tour.
Hours before the news was announced, Barker shared a series of snaps on his Instagram Story of him visiting a prayer room. After posting a picture outside the room, Barker then shared two photos inside the space, one of a stained-glass window and another of a blue banner reading, “Together We Pray.”
On Thursday, he had also posted a shot of the band’s tour bus and covered up the license plate with the words, “DON’T TRUST ANYONE.”
The couple announced their pregnancy news during the first Los Angeles stop of Blink-182’s tour.
While in the audience of the June 16 show, Kardashian, 44, held up a handwritten black and white sign reading, “Travis I’m Pregnant” as a camera zoomed in on her in the crowd.
Barker and Kardashian shared a video of the moment on their Instagram accounts, and one of Barker’s bandmates could heard saying, "Someone's having a baby!"
The inspiration for the sign came from the band’s music video for their 1999 track “All The Small Things” which features a fan holding up a yellow and black sign that also reads, “Travis I’m Pregnant.”
And just weeks later the pair revealed the news that they're expecting a baby boy during a sex reveal party attended by their family and friends.
The bash had a music tour theme and guests were even given tour passes reading, "Baby Barker World Tour with Special Guest Kravis. All Access.”
