Yes, Sir Attenborough will be gracing Graham's red sofa tonight for a night of laughs, wit and red chairs.
David recently lashed out at Donald Trump for claiming climate change was a "hoax" - so we expect he'll be talking about that. And we're looking forward to it, a lot.
Ben Affleck will also be there, to promote his new movie The Accountant.
Claire Foy will be promoting the new drama she stars in The Crown, alongside co-star Matt Smith.
This weeks music will be coming to you courtesy of Sting. He'll play at the official re-opening of The Bataclan in Paris, so will be talking a little bit more about that.
All stellar guests don't get us wrong. But we just can't wait for DAVID.
