Travis Barker was brought to the hospital along with Kourtney Kardashian, his wife.
He had messaged his fans that "God saves" him.
The 46-year-old Blink-182 drummer was photographed on a stretcher outside Cedars-Sinai Medical Center while his reality TV veteran partner, 43 walked beside him.
As he was being wheeled from the ambulance, he held his right hand up and revealed his distinctive skull tattoo.
Kardashian was seen only from her back, wearing black head-to-toe with a hoodie over her head.
As Barker arrived at Los Angeles' hospital, her security team followed Barker in a Range Rover black.
Two vehicles appeared to have entered through an incorrect entrance. Hospital workers then directed them to another area.
Barker and Kardashian arrived at West Hills Hospital & Medical Center on Tuesday morning local (29.06.22), to receive treatment for Barker’s mystery condition.
Barker's tweet "God Save Me" at 10.45 AM local time was apparently sent during a medical emergency.
PEOPLE was told by a source that they are currently seeing one another, but it is still in its early stages.
