Bradley Walsh as Tony Bennett(01 of20)
Open Image ModalLong before finding success as the host of 'The Chase', Bradley played Danny Baldwin in 'Coronation Street', and took part in a Soap Stars special of 'Stars In Their Eyes' in 2005.
Eleven years on from paying homage to Tony Bennett, he'd release his first ever collection of swing standards, which would eventually be named 2016's highest-selling debut album. (credit:Ken McKay/Rex/Shutterstock/ITV/David Redfern/Getty)
Kerry Katona as Marilyn Monroe(02 of20)
Open Image ModalOf course, if it's a TV show with 'celebrity' in the title, you can bet your bottom dollar that Kerry will have starred in it at some point or another.
In the 2006 Christmas special, she channelled Marilyn Monroe for a performance of 'Santa Baby' (not letting the fact that Marilyn never actually had a version of 'Santa Baby' slow her down for even a second). (credit:Dave J Hogan/Getty/Sunset Boulevard/Corbis)
Stephen Mulhern as Robbie Williams(03 of20)
Open Image ModalHe may now be known as one of the safest faces on telly, but in 2005, Stephen Mulhern showed off a very different side for this bare-chested rendition of 'Let Me Entertain You'. (credit:Barcroft Media/Getty/Rex/Shutterstock/ITV/Vevo)
Carol Vorderman as Cher(04 of20)
Open Image ModalIn the very first ever celebrity edition of 'Stars In Their Eyes', Carol threw on a leather skirt and the biggest wig she could lay her hands on to perform 'The Shoop Shoop Song' as Cher. (credit:Michael Ochs Archives via Getty Images/ITV/Rex/Shutterstock/David M Bennett)
Beverley Callard as Cher(05 of20)
Open Image ModalWhile we're big fans of Vorders, it's hard to deny that she was outshone by Beverley Callard's efforts as the 'Believe' diva six years later.
Bev went the whole shebang with her outfit, even recreating the leather jacket and revealing leotard video Cher sported in the 'If I Could Turn Back Time' music video. (credit:Sipa Press/Rex/Shutterstock/ITV)
Jerry Springer as Elvis Presley(06 of20)
Open Image ModalOne of a few international stars to appear on 'Stars In Their Eyes', Jerry (Jerry! Jerry!) crossed the Atlantic to pay tribute to the King, singing 'Can't Help Falling In Love'. (credit:ITV/Rex/Shutterstock)
Suranne Jones as Madonna(07 of20)
Open Image ModalBack when her 'Doctor Foster' TV Bafta was still barely a glimmer in the distance, Suranne was best known to 'Corrie' fans as machinist Karen McDonald.
In 2001, she and a number of her co-stars appeared in a 'Coronation Street' special of 'Stars In Their Eyes', and here she is giving her best Madonna. (credit:John Philips/Getty/ITV/Rex/Shutterstock/YouTube)
Jane Danson as Madonna(08 of20)
Open Image ModalBut Suranne wasn't the only lady of Weatherfield to put her spin on the Queen Of Pop, with the Leanne Battersby actress winning the Legends special with her take on Madonna's 'Frozen'.
Take that, Rhona Cameron as Judy Garland. (credit:Stuart C Wilson/Getty/Eugene Adebari/REX/Shutterstock)
Eamonn Holmes as Johnny Cash(09 of20)
Open Image ModalWhile we're sure Ruth Langsford would probably rather put this to the back of her mind, Eamonn put his all into his performance as Johnny Cash, singing (what else?), 'Ring Of Fire'. (credit:Sipa Press/Rex/Shutterstock/ITV/Steve Meddle)
Yvette Fielding as Annie Lennox(10 of20)
Open Image ModalThat same year, 'Blue Peter' presenter and paranormal aficionada Yvette Fielding dug deep for her interpretation of Annie Lennox's 'No More I Love Yous'.
They both lost out to Dale Meeks and Mark Charnock (us neither), who performed as The Blues Brothers. (credit:Rex/Shutterstock/ITV/Vevo)
Brian Blessed as Luciano Pavarotti(11 of20)
Open Image ModalSometimes, the 'Stars And Their Eyes' team had their work cut out for them, and spent hours transforming celebrity contestants with the help of make-up, wigs and sometimes even prosthetics.
Other times... this was less necessary. (credit:SAV/Getty/ullstein bild/ITV/Rex/Shutterstock)
Harry Hill as Morrissey(12 of20)
Open Image ModalSelf-confessed Smiths devotee Harry Hill's appearance gave 'Stars In Their Eyes' one of its most memorable moments ever, when he performed 'This Charming Man' while swishing his flowers and tossing his quiff in true Morrissey fashion.
The illusion was only slightly broken by the fact he kept his specs on the whole time, mind you. (credit:Photoshot/Getty/Rex/Shutterstock/ITV/Martin ONeill)
Denise Welch as Petula Clark(13 of20)
Open Image ModalOn the same bill as Harry Hill was then-'Coronation Street' star and forever-HuffPost UK favourite, Denise Welch, who performed 'Downtown' as Petula Clark. (credit:Ken McKay/Rex/ITV/Shutterstock/George Konig)
Paul Burrell as Richard Gere(14 of20)
Open Image ModalIn the last ever celebrity Christmas special, Paul Burrell gave viewers a touch of musical theatre, throwing on his best tuxedo to perform 'Razzle Dazzle' from 'Chicago'. (credit:Miramax/Producers Circle/Storyline Entertainment/REX/Shutterstock/ITV/Ken McKay)
Alison Hammond as Nina Simone(15 of20)
Open Image ModalWhat can we say? Marvellous. (credit:Ken McKay/Rex/ITV/Shutterstock/David Redfern/Getty)
Al Murray as Neil Diamond(16 of20)
Open Image ModalHe swapped his usual Pub Landlord attire for some 1970s garb and ditched the trademark pint glass for a guitar, but we'd still recognise him anywhere. Even in that wig. (credit:John Phillips/Getty/ITV/Rex/Shutterstock/Andre Csillag)
Lisa Riley as Stockard Channing(17 of20)
Open Image ModalWe've got one word for that jacket. Flammable. (credit:Paramount/Rso/REX/Shutterstock/Ken McKay/ITV)
Linford Christie as Ray Charles(18 of20)
Open Image ModalHaving already more than proved himself as an Olympic runner, Linford Christie tried something a bit different when 2000, when he gave singing a go.
Sadly, his Ray Charles was no match for Claire Sweeney's Celine Dion. (credit:Can Nguyen/REX/Shutterstock/ITV/Mark Downey)
Esther Rantzen as Edith Piaf(19 of20)
Open Image ModalIn one of the more cultured 'Stars In Their Eyes' moments, Esther Rantzen performed a song entirely in French when she gave a rendition of Edith Piaf's 'La Vie En Rose' in the show's Divas Special. (credit:Bettman/Getty/ITV/Rex/Shutterstock/James M Warren/Silverhub)
David Neilson as Roy Orbison(20 of20)
