We're guessing Emily Blunt was unavailable.
'The Late Late Show with James Corden' is on a break along with the rest of late night this week but that hasn't stopped Bilbo Smuggins from dropping some "content" on the internet, this time with the help of James Blunt.
And while we always appreciate some deadpan James Blunt (he's redeemed himself from inflicting the pain of 'You're Beautiful' on the world with his Twitter behaviour), the fatal flaw in this sketch is that we don't think Corden would ever have any problem telling people working for him what he thought of him.
Just ask Patrick Stewart.
