AceShowbiz - Kid Cudi is praying for Travis Barker amid the drummer's apparent pancreatitis diagnosis. After the Blink-182 musician was hospitalized for a reported inflamed pancreas said to have been "triggered" by a colonoscopy, the "Pursuit of Happiness" rapper sent "love" to his long-time friend.

On Wednesday, June 29, Cudi tweeted, "Travis I love u and im prayin for u." The 38-year-old rapper and the 46-year-old drummer have been friends for years and collaborated on the latter's 2011 song "Cool Head".

Several of Cudi's fans flooded his comment with well-wishes for Barker. Cudi, who is born Scott Ramon Seguro Mescudi, retweeted the comment, "Prayers up for Travis Barker." A second supporter said, "hope all is well, throwing this in rotation. prayers out to travis and his family."

A third, in the meantime, referenced a 2008 accident in South Carolina Barker managed to escape with severe burns by saying, "If he survived a plane crash then he can survive whatever this is."

A source told PEOPLE on Wednesday Barker's new wife Kourtney Kardashian is refusing to leave his side in hospital. The insider added, "Kourtney was worried yesterday (June 28). They both were. Travis was suffering from extreme stomach pain and could barely walk."

Barker is still in medical care at Cedars-Sinai Medical Center, Los Angeles, California. He was raced to West Hills hospital on Tuesday, June 28 before being transferred to the facility. He was pictured being wheeled into Cedars-Sinai after tweeting, "God save me," at around 10.45 A.M. local time on Tuesday.

The incident came weeks after Barker and mum-of-three Kardashian, who has 12-year-old Mason, 9-year-old Penelope and 7-year-old Reign with ex-partner Scott Disick, got married in Portofino, Italy. They initially wed in May following practice nuptials in Las Vegas in March, before holding the third ceremony for family and friends in Italy.
