Knock Knock, Who's There? It's Ryan Seacrest's 'Knock Knock Live' Instagram Takeover

Get ready for the mother of all knock knock jokes. Ryan Seacrest and a crew of celebrity pals are getting ready to surprise some unsuspecting — and deserving — people all across the country with the new Fox reality show Knock Knock Live. But even a live show (er, especially a live show) requires some rehearsal time, so Seacrest did double duty and took over Yahoo TV’s Instagram account during rehearsals for Knock Knock Live. And — no joke — we can already see he’s taking the task of giving people unexpected good news very seriously.

The American Idol host posted shots of some of his famous accomplices, including Kellie Pickler and Ross Matthews, who was working in a secret location for the rehearsal, but will actually be “hiding in the bushes outside someone’s house” during the live show. Seacrest also shared a sneak peek of the Knock Knock Live set, as well as a stack of completed paperwork that we can only assume he spent all night working on because, well, he is the hardest working guy in television.
