The BBC must've been delighted with the first series of Russell Kane's Live at the Apollo-for-yoofs - a third season is already in production, before the second batch has even aired. The format remains largely unchanged for Live at the Electric 2.0: Kane introduces a mix of character comics and sketch acts with a younger, trendier edge than McIntyre's relatively geriatric affairs.

But, wisely, most of the pre-edited VTs that lead the first series have gone, replaced by greater focus on the 'live' part of the title. Welcome new additions to the line-up include suave French misanthrope Marcel Lucont (the character creation of Alexis Dubus), who dishes out some inventive sex advice, and weirdo Northern Irishman Paul Currie, who silently, and absurdly, recreates the iconic Russian roulette scene from The Deer Hunter with the help of a monkey puppet and some theatrical gestures.

Not all the skits hit the mark, though. YouTube star Chris Kendall (know as 'Crabstickz' on the interwebs) spoofs Robert Pattinson's Twilight turn about five years too late, and Kane's own The Only Way is Shakespeare sketch has one joke: saying rude words in a thespian tongue. But the rotating cast make this well worth sticking with, and there are some cracking acts to come later in the series.

Kristen Stewart, star of Twilight, never looks particularly happy, so here's hoping she cheers up a bit when she arrives on Norton's sofa. Stewart, well-known as the inamorata of her co-star Robert Pattinson, is in the studio to promote her new film Snow White and the Huntsman.

They will be serenaded by Engelbert Humperdinck, singing UK Eurovision entry Love Will Set You Free. In the comedy corner is the mighty Chris Rock, talking about his new movie, the animated kids' comedy Madagascar 3: Europe's Most Wanted.

Even before the final instalment of The Twilight Saga - Breaking Dawn, finished shooting, British actor Robert Pattinson had moved on to bigger things.

His co-star in his latest film, which opened this week, is a pretty 600 stone elephant called Tai.

Sadly, Graham Norton's sofa probably won't be large enough for Tai to join him on the show tonight. Instead, he'll have to settle for Robert's other co-star from Water for Elephants - Reese Witherspoon. This is actually the second time the two have worked together, because despite the tiny age gap between them, Robert was actually cast as her son in the 2004 movie Vanity Fair. It was a less than auspicious start to his Hollywood career though because his scenes were ­eventually cut from the film and can only be seen in the DVD version.

We're sure Graham will be quizzing Robert and Reese on their love scenes together in Water For Elephants.

But the relationship R-Patz fans really want to hear about is, of course, the one with his Twilight co-star and real-life girlfriend Kristen Stewart.

Don't hold back, Graham - we want to hear everything.
