50 Cent on QVC: With his success in the charts waning recently and being muscled out of the game by, well, better rappers, when the 'In Da Club' hitmaker announced he was going to appear on grandma's favourite shopping channel QVC to flog his headphones, it was met with a collective jeer. However, Fiddy had the last laugh, flirting with the female presenters and making a cool reported $177k.

Alex James and his cheese: The Blur bassist turned his hand to cheesemaking and journalism, with mixed results. He has a range of everyday cheeses at Asda, including flavours such as 'cheddar and salad cream' and 'cheddar tikka masala'. Unsurprisingly, these have not been well recieved, with The Guardian food critics calling them 'bizzare'. James also penned a controversial column about how great McDonald's and KFC are. In a further bid to seemingly decrease his popularity, he was photographed with David Cameron and Jeremy Clarkson in a image suppurating with smug and horror.

Duffy promotes Diet Coke: Remember soul singer Duffy? No? Well then, you may or may not remember in 2009 when the 'Mercy' singer, whose career was seemingly on the up after a best-selling debut album, ill-advisedly starred in a truly terrible Diet Coke advert. She released a second album afterwards...it fell flat, like Coke on a kitchen worktop.

Steven Tyler on American Idol: There was some overall confusion when the ex-heroin addict lead singer of one of America's most famous hard rock bands, Aerosmith, joined the judging panel of shiny happy Simon Cowell-engineered American Idol alongside R&B singer Jennifer Lopez. However, things worked out well for the singer, nicknamed the "Demon of Screamin'", with sales of Aerosmith's music skyrocketing by 250 per cent when Tyler joined the show in 2010.

Manic Street Preachers do Strictly Come Dancing: What with their political and intellectual lyricism, the Welsh band were the last people you'd expect to see thrashing around on the camp, glitzy BBC dancing competition, whilst a dozen perma-tanned D-list celebrities shuffle around in the foreground. But it actually happened. The appearance was met with a mixed reaction from the band's loyal fanbase, with one commenter announcing "rock is now dead", while others others realised the Manic's intended "less shot at mass communication".

John Lydon promotes Country Life butter: The lead singer of the infamous, anarchist punk band the Sex Pistols popping up on an advert promoting a dairy product made everyone collectively choke on their tea. He was, of course, accused of selling out, but Lydon, the artist formerly known as Johnny Rotten, defended himself, stating "I thought it was very anarchic of the dairy company to want to attach themselves to me." It also funded the latest PiL album and tour, which kinda makes everything seem OK.

Ringo Starr narrates Thomas the Tank Engine: What does one do after being in the biggest band of all time? Obvious! You narrate the TV cartoon version of Thomas the Tank Engine of course, and become the soothing, if monotonous, voice of our childhoods. Nobody argued with this, because he's Ringo bloody Starr.

Iggy Pop sells car insurance: The 'Godfather of punk' attracted criticism for starring in the 2009 adverts for insurance firm Swiftcover. The most disturbing thing though was the terrifying Iggy Pop puppet sidekick which jiggles around alongside him like a horrifying scene from your nightmares. He was dropped in 2011, replaced by animated dogs voiced by Bez from the Happy Mondays and Noddy Holder of Slade fame.

Ricky Wilson joins The Voice: It was announced today the shouty-voiced frontman of the Kaiser Chiefs would be joining the BBC's 'credible' singing contest, alongside Kylie Minogue, will.i.am and Tom Jones, who is possibly too old to run for the hills like Jessie J and that man from The Script wisely did. The decision was met with a mixed reaction, with one Twitterer asking "What does Ricky Wilson know about singing?" while another Kaisers fan added "Ricky Wilson joining The Voice for 2014, makes it actually worth watching."
