Travis Barker will continue to be monitored by doctors after being admitted to hospital with crippling stomach pain.
The Blink-182 drummer is being treated at Cedars-Sinai Medical Center in Los Angeles for suspected pancreatitis.
A source close to the couple told PEOPLE that they were both extremely worried about Barker's condition. "Travis was suffering from extreme stomach pain and could barely walk," they said.
Barker's daughter Alabama asked her Instagram followers to "send your prayers" for her dad after he was taken to hospital.
The rocker made a short but concerning social media post on June 28, which simply read: "God save me".
His new wife Kourtney Kardashian has been accompanying Travis through his ordeal and "will not be leaving his side", a source told the Sun.
The source said that Travis was "set to be released from hospital on Sunday, but this could change depending on his recovery", adding that he is "doing well".
According to TMZ, doctors believe his pancreatitis could have been "triggered" by a recent colonoscopy,
The drama comes just a month after Barker and Kardashian tied the knot in a lavish ceremony in Italy.
B arker 's ex-wife Shanna Moakler wished Travis a "speedy recovery".
The former model, who was married to the drummer between 2004 and 2008, told TMZ: "Thank you to everyone who has reached out with concern to my ex and father of my children, I know he is in great hands and surrounded by loving support and the best medical teams available and his beautiful wife Kourtney.
"I pray for a speedy recovery and for the comfort of my children as I know they are very concerned and worried.
"Travis has beat the odds numerous times and I know with his support system he will do it again. I will always be there for him and my children."
Travis's step-daughter Atiana De La Hoya, 23 - the daughter of Shanna and former boxing champ Oscar De La Hoya - took to social media to acknowledge the "outpouring of love" for the musician.
