Career: Like bread and butter, Giedroyc and Sue Perkins go well together - in fact, they're almost inseparable in professional terms. They were a hit at the Edinburgh Festival in 1993, and went on to write scripts for French and Saunders before presenting comedy chat show Light/Late Lunch and RI:SE. She was also in the children's sketch show Sorry I've Got No Head. More recently she has scored another hit with The Great British Bake-Off, alongside Sue, and daytime ITV show, Mel and Sue. Her radio work has included The 4 O'Clock Show on Radio 4 Extra.

Career: Llewelyn-Bowen worked for a large interior design company before setting up his own consultancy, winning several high-profile clients. His wife recommended him to a TV producer friend, which led to appearances on Changing Rooms, where he became famous for his outlandish taste. While most of the show's participants loved his colourful creations, some were decidedly unimpressed. He also appeared on Home Front, Taste and Real Rooms, before taking over as Changing Rooms' host from Carol Smillie. More recently, Laurence has been a judge on Popstar to Operastar, and presented daytime ITV show House Gift. In August 2013, he was a contestant on ITV dancing reality series Stepping Out with his wife Jackie - they finished third.

Career: Van Outen became a household name and lads mag favourite thanks to spells on The Big Breakfast and sitcom Babes in the Wood. Films such as Tube Tales and Love, Honour and Obey met with a lukewarm reception. Her stage work has been better received. She wowed the critics with her performance in Chicago, both in London and New York. Other West End roles include Tell Me on a Sunday, Rent Remixed, and Legally Blonde. She co-hosted Grease: You're the One that I Want for NBC in America in 2007, but was forced to take elocution lessons because the American audience did not warm to her Essex accent. Van Outen had better luck when she appeared on the panel of BBC1's Any Dream Will Do! which was casting Joseph in a new production of Joseph and the Amazing Technicolor Dreamcoat. She reunited with former Big Breakfast colleague Johnny Vaughan in 2008 as a co-host of the breakfast show on Capital Radio, but she quit a few months later half-way through her contract. In 2012, she partnered with professional dancer James Jordan on Strictly Come Dancing.
