Kourtney Kardashian is sticking by her husband, Travis Barker's side in sickness and in health. "Kourtney won't leave his side," a source told People. The 43-year-old reality star was seen following the Blink-182 drummer as he was taken to the hospital on Tuesday with Pancreatitis. "Kourtney was worried yesterday. They both were," the source said. "Travis was suffering from extreme stomach pain and could barely walk." However, the insider told the outlet that Travis is "getting the best care at (Cedars-Sinai) though" and that doctors are focusing on his pain management and determining his condition through tests and a modified diet.
