Madonna talks marriage, movies and motherhood and reveals what she really thinks of Lady Gaga in the interview Graham Norton has been waiting all his career to get.

When it was first announced that Madge would be gracing his show with her presence, he exclaimed: "I may have to retire!" In the interview, which was prerecorded on Wednesday, Madonna also reveals the brilliant title of her next album.

But the real reason she's on the show is to plug her new movie, W.E. - her uniquely personal take on the Wallis Simpson story.

That Madonna thought it necessary to join the film's stars Andrea Riseborough and James D'Arcy on Graham's sofa should give you a rough idea of what a thorough pasting this movie has got from the critics, but that's by the by.

Expect Olympic levels of glitter, fanfare and A-list excitement on Graham Norton's show tonight, as Madonna, shape-shifting queen of pop, arrives in the studio to discuss her life, career and the forthcoming release of W.E. - a romantic drama about the life of Wallis Simpson, which she co-wrote and directed. James D'Arcy and Andrea Riseborough, who play King Edward VIII and Simpson, also drop in to talk about their roles.
