The stars of American Reunion are in Britain to promote the latest film in the franchise, and Klein – along with Eddie Kaye Thomas and Jennifer Coolidge – sat down for a chat with This Morning hosts Phillip Schofield and Holly Willoughby.
But the worldwide promotion of the movie has left Klein feeling unwell.
Thomas revealed, “London has made my pal Chris Klein a little sick, it took his voice away.”
Klein added, “I’m a little bit sick – it wasn’t London that did it, it’s just all the running around.”
The actor then talked at length about the American Pie franchise, prompting Thomas to quip, “It’s the most he’s said all morning! He’s been telling us all morning that he can’t speak, he’s been saving it for you guys.”
A few minutes into the chat, Klein’s voice started to wane, causing Coolidge to chuckle, and the actor joked, “Are you laughing at my voice?”
He later added: “It sounds worse than it is.”
