Michelle Keegan talks about her role in Plebs

Tomorrow, audiences will get to see Michelle Keegan's first comedy turn in Plebs, as a vestal virgin who is frustrated she has never left Rome - or eaten a kebab.

Plebs is back: sharply written, funny & filthy as ever

Series three of the ITV2 comedy sees Marcus, Stylax and Grumio on the wrong end of a lion, while guest stars Maureen Lipman and Michelle Keegan shine.

The return of a wilfully stupid format, which asks comedians to relate tales of yore while plastered. Other performers then star in scenes reflecting exactly what the soused comic has said, lip-syncing to any dialogue. It's a way to make improvised comedy less reliable. Not much comes of Jack Whitehall and Michelle Keegan as Walter Raleigh and Elizabeth I, but Robin Hood and Maid Marian, played by Mathew Baynton and Emma Bunton to the blazingly profane imaginings of Tom Davis, is sensational.

Michelle Keegan to appear in Plebs as 'vestal virgin'

Former Coronation Street star Michelle has already filmed the small part in Bulgaria, where the cast and crew 'loved' her.

Interview with Jason Manford

When Jason Manford was shooting the series Ordinary Lies, rumours swirled that he was playing Michelle Keegan's husband. He wasn't, but he found people's bemused reaction a little insulting. "I was more offended that people thought it wasn't believable!" jokes the 34-year-old. "But hang on a minute, I don't have to be good-looking - I'm funny."

Kelly Brook: 'Keith Lemon wanted Michelle Keegan'

Kelly Brook has revealed that Keith Lemon told her he wanted Michelle Keegan to join Celebrity Juice instead of her.

The dead-fly garnish on this week's bucket of swill was Anonymous, the new celebrity prank-show on ITV1.

"What happens when celebrities want a day off?" the introduction ran - to the immediate, incredulous answer from the viewer, "Take the day off?"

But this was not the full question Anonymous was asking. The full inquiry was, "What happens when celebrities want a day off - and cause havoc with dozens of cameras, ingeniously hidden from view?"

Well then, in that case, the answer is obviously, "Fill up 45 minutes of prime-time on a Saturday night and, technically, not really have a day off at all."

The "killer" idea of Anonymous is that it gives celebrities "the biggest makeover - a new face". Thanks to a much-mentioned "five hours in prosthetics", Fiz from Coronation Street got rigged up as a blonde Essex girl, the X Factor judge Louis Walsh got disguised as an old man, and the former rugby player Matt Dawson was transformed into a camp West End choreographer. Thus disguised, the celebrities then pranked their celebrity friends - usually by behaving with intolerable wackiness, while their friends acted with bemused good grace.

The essential problem with Anonymous - and it became obvious in minutes - was the disguises themselves. While the stars certainly weren't recognisable as themselves, they also weren't necessarily recognisable as normal human beings, either. Frankly, those prosthetics were poor. Fiz's chin looked like it was constructed of three pieces of pre-sliced turkey breast. Matt Dawson's face had the alarming unyieldingness of a Bakelite death mask and Louis Walsh looked like a statue of Freddie Boswell from Bread, as sculpted by the blind woman in the video to Hello. Even in a post-Simon Weston world, you would momentarily break stride on sighting them in the street. And in every single prank, the victims commented on how alarmingly awful the prankers' prosthetics were.

"As soon as I saw him, I thought, 'He's had loads of plastic surgery,'" Austin Healey said of Dawson's wonky-Spam head.

"I just thought you'd had really bad plastic surgery!" Fiz's Corrie colleague Michelle Keegan howled at Fiz, who looked like Nikki Chapman wearing Craig David's Bo' Selecta! chin.

You do have to wonder if the muchvaunted Anonymous "Four hours in prosthetics!" is strictly necessary. After all, Jeremy Beadle regularly managed to get people's houses knocked down while wearing disguises no more audacious than "a hat".
