Graham Norton

After her scene-stealing performance in The Devil Wears Prada, British actress Emily Blunt was tipped for stardom. Now she's making good on her early promise, joining bawdy chat show king Graham Norton to talk about her latest spate of big-budget movies. Sassy starlet Rihanna also drops by for a chat and performs her latest Calvin Harris-helmed hit Where Have You Been.

What a fragrant and lovely Graham Norton couch this week as pop songstrels Katy Perry and Cheryl Cole take their dainty places. Ubiquitous comedian Ross Noble is also a guest, the thorn between two roses.

Cheryl Cole, after a difficult couple of years, including her marital problems and all of that unpleasantness over her here today/gone tomorrow role as a judge on the US X Factor, is back in the limelight again. She'll be singing her new single, Call My Name.

The hard-working Katy Perry has also had her fair share of personal troubles, what with the collapse of her brief marriage to Russell Brand. But she seems to be on the up, and will be promoting her concert-tour documentary Katy Perry: Part of Me 3D.

Growly Alastair Campbell, former Downing Street director of communications and strategy, diarist, Burnley supporter and ebullient Tweeter, chairs for the first time. So expect lots of needling from Ian Hislop, who'll doubtless have something to say about Campbell's appearances before the Leveson Inquiry (he's the first of tonight's Leveson alumni; Steve Coogan turns up on Graham Norton).

But the big question is will Campbell have the skill to rein in guest panellist, big, loud hirsute Ross Noble, who tends to overwhelm any panel show he's on if he's not kept in order? Returning to the show is Lord Sugar's flint-eyed right-hand man, and Countdown host, Nick Hewer.

Steve Coogan's last big attention-grabbing television appearance saw him sober-suited and angry giving evidence about press intrusion and phone-hacking to the Leveson Inquiry last year.

Tonight he joins Charlize Theron and Jon Hamm on Graham Norton's big red sofa, presumably to discuss his travails at the hands of an unforgiving press and the return of his monstrous, brilliant creation, embittered Radio Norwich DJ Alan Partridge. There will be a Partridge film later this year and a TV series is set for Sky Atlantic.

Monarchs of the entertainment world rather than royalty are the subject of this engaging three-parter celebrating some of showbusiness's most flamboyant performers. It does promise some serious intent, reflecting on how the likes of Paul O'Grady, Graham Norton and Elton John have changed attitudes to homosexuality. But it's the performances from the archives that really glitter.

This opener looks back to the Dark Ages in 1952, and features such shining stars as Danny La Rue and Liberace. Contributors include Cilla Black, Julian Clary, Ronnie Corbett, Boy George and Arlene Phillips.
