Speaking to PEOPLE, later on, Dustin's team added: "It's very serious, though we are still waiting for more details, which we will have shortly. He's in a lot of pain."
And talking to Entertainment Weekly, his representative confirmed that the star is "undergoing chemo" for cancer and will remain at the hospital for "at least another week and then we will figure out when he gets to come home."
"By next week, we'll have a much better understanding of the severity of his condition and what treatments he will need so that he's comfortable."
