Jack Whitehall will takeover The Graham Norton Show for a special episode this month.
It'll be the first time that Graham has missed a show, stepping down for a week in order to present UK coverage of the Eurovision Song Contest grand final.
On May 17, Jack will takeover to chat with guests including Game of Thrones and Star Wars star Gwendoline Christie, as well as Luke Evans and Paloma Faith.
Jack said: "I was so honoured Graham asked me to do this for him. The thought of stepping into his huge showbiz boots fills me in equal measure with fear and excitement.
"Worst case, I will make everyone appreciate just how lucky we are to have him."
Graham said: "I'm thrilled to know that I am leaving the show in Jack's capable hands. He is bound to do an amazing job.
"I should warn him not to get too comfortable in my chair, though, because like a slightly fey terminator, I'll be back!"
The Graham Norton Show currently airs Fridays on BBC One from 10:35PM.
This week's episode will feature Graham chatting to guests Keanu Reeves, Kylie Minogue, Suranne Jones, Taron Egerton, and Jamie Bell.
As always, the show will be filmed in front of a live audience as Graham chats to his guests.
If you can't catch it live on TV, you can watch live online or catch up on BBC iPlayer.
Meanwhile, if you want to watch The Graham Norton Show being filmed, you can get yourself free tickets.
Tickets can be requested from SRO Audiences.
