Good thing Matt Damon was nowhere to be found!
Jimmy, 45, said the "last two days have been a roller coaster."
"Last night, Matt Damon hijacked the show, and today I'm getting a star on Hollywood Boulevard," he said, noting that he had "some concern" Matt would hijack Friday's event.
Ever humble, he even joked that "people will pee on my star."
You have our word, Jimmy, we'll never do that.
