Talk show host Nate Berkus has been hospitalized and is expected to undergo surgery for appendicitis.
“He was on the Today show this morning and he wasn’t feeling well,” a rep for the company that produces The Nate Berkus Show tells PEOPLE exclusively. “He powered through and then went straight to the hospital after that and they learned he had appendicitis.”
Berkus, 39, had complained that he was under the weather, but didn’t cancel his appearance. “He was in a lot of pain,” adds the rep. “I don’t think people realized how ill he was.”
This will mean a schedule setback for the Oprah Winfrey disciple, whose own show debuted in September.
