It may just be the campest and most hilarious Graham Norton Show yet with this lineup, which means it really is an unmissable affair, but sure when is it not?
Graham will be meeting singing superstar Dame Shirley Bassey, who is gearing herself up to perform at the Royal Variety Performance next week. Shirley's just a bit of legend really and is the woman responsible for Bond hits like Goldfinger, Diamonds are Forever and many more.
Joining Shirley on the couch will be actor and comedian David Walliams, who you will also know as a Britain's Got Talent judge and Simon Cowell's biggest fan... Stevie Ritchie better watch out.
As well as that pair, there are two more talented comedian/actors on the show as Catherine Tate and The IT Crowd's Richard Ayoade will be on the couch.
Finally, the cherry on top will be a performance from yet another legendary singer as Annie Lennox takes to the stage to sing God Bless the Child.
Oh and if you haven't heard already, you can also catch Graham over on The Late Late Show tonight as he chats to Tubbers about his new book. Maybe they can have a chat show host-off...
