Cudi and Barker, 46, previously collaborated in the 2011 song "Cool Head" — which was featured on Barker's album Give the Drummer Some — and have remained pals since.

The "Mr. Rager" singer's message comes after Barker was seen getting wheeled into Cedars-Sinai Medical Center in Los Angeles on a stretcher.

On Wednesday, PEOPLE confirmed that the punk-rocker is suffering from pancreatitis, an inflammation of the organ that aids in digestion and regulating blood sugar. TMZ was first to report the news.

Meanwhile, an insider told PEOPLE Wednesday, "Kourtney was worried yesterday. They both were."

Barker's 16-year-old daughter, Alabama, asked her followers to "please send your prayers" in an Instagram Story posted shortly after her dad was taken to the hospital.

Alabama also shared a since-deleted post to her TikTok page with a similar sentiment. Alongside a photo of herself holding her dad's hand while he was seated in a hospital bed, she wrote, "Please say a prayer," Daily Mail reported.

Hours after Barker went to the hospital, his 18-year-old son Landon was seen performing his collaboration "Die in California" with Machine Gun Kelly, at his Mainstream Sellout Tour concert at Madison Square Garden in New York.

PEOPLE editor Nigel Smith, who attended the concert, said Landon seemed "very emotional" after coming out on stage for a second song inspired by the recent death of his friend Cooper Noriega, a TikTok star who died at 19 on June 9. At one point, Landon shared an embrace with MGK, a family friend who attended Travis and Kardashian's May wedding in Italy.

"Landon came out during the song and seemed to be working out some demons," he said. "They hugged onstage during the performance, singing and shared an emotional moment at the end of the song before Landon walked off."
