Here's Who's on Tonight's Graham Norton Show...

Lovely lineup in store on tonight's Graham Norton, although it may get a bit hectic on that couch by the end with all this lot.

First up, nature's living legend himself is on the show. At this stage, there's not an insect or elephant in the world who hasn't copped off to the dulcet tones of this man's voice, as Sir David Attenborough joins Graham for a chat!

We could listen to this man read the phone book.

Joining his good self will be the stunningly talented Jessica Chastain, did you know someone told her once she wasn't pretty enough to be an actress? Fools! She's a knock-out and one of Hollywood's greatest leading ladies at the moment if you ask us. She's currently starring in A Most Violent Year, a role for which she received a Golden Globe nomination.

Also on the couch, will be sports presenter, former footballer and Walker's crisp eater Gary Lineker. While Harry Hill will also be along to provide a few laughs and to chat about his latest TV gig presenting a new take on 'Stars in Their Eyes'.

There they all are now...

Later then, supergroup McBusted will be providing the music and then somehow squeezing onto the couch afterwards to watch a bit of Rec Chair action.

The Graham Norton Show is on tonight at 10.35pm, but do bear in mind that times may vary between BBC1 and BBC1NI.
