Natalie Portman

Everyone loves sparks flying on the chatshow circus and the best chance of a meltdown tonight looks likely to come from the wayward Britney Spears as she drops by for a chinwag with Alan Carr.

Will he ask her opinion on twerking Miley Cyrus? Also making merry with Carr are Olympic hero Mo Farah and actor Joseph Gordon-Levitt, plus music from Jake Bugg, while Graham Norton has landed Paul McCartney, Natalie Portman, Chris Hemsworth, James Corden and Katy Perry.

As usual, Norton's bookers have activated their tractor beam to draw in the best celebrities. For a start, Paul McCartney is on the couch! Our greatest living songwriter (discuss) will talk about his new album, helpfully entitled New, and give us a sample - most likely the Beatles-y title track, which sounds like a breezy relative of Got to Get You into My Life.

At the other end of the pop spectrum is Katy Perry - she has a new album out soon. And let's not forget the actors: Natalie Portman talks about her role in Thor sequel, The Dark World and if that wasn't enough star wattage, James Corden drops by.
