Career: Carr made his TV debut as a guest on the ITV lunchtime show Today with Des and Mel. He came to true prominence on Channel 4's The Sunday Night Project with Justin Lee Collins. He makes regular guest appearances on panel shows such as 8 Out of 10 Cats and Never Mind The Buzzcocks and has featured as a panellist on Channel 4's annual Big Fat Quiz of the Year, a staple of the Christmas TV schedules. He has also fronted his own game show, Alan Carr's Celebrity Ding Dong, written his autobiography, and continues to perform stand-up. His Channel 4 show Chatty Man attracts some of the biggest names in showbiz and has been a staple of the Channel 4 schedule since 2009. He also presented a weekly programme on Radio 2 for three years, and fronted game show The Singer Takes It All. In 2016, he hosted Alan Carr's Happy Hour, which was a spin off of Chatty Man.

Career: Davina started out as a singer (her demo was produced by Eric Clapton) and worked for the Models One agency before securing a presenter's job on Ray Cokes' Most Wanted on MTV Europe. ITV's middle-of-the-night series God's Gift led to the higher profile Streetmate, Don't Try This at Home and Popstars: The Rivals, although she tasted failure with her sitcom Sam's Game, series He's Having a Baby, and her self-titled BBC chat show. She's also fronted Love on a Saturday Night and co-hosted both Sport Relief and Comic Relief. Big Brother remains her biggest hit (she quit after 11 series as host in 2010), but has another hit on her hands with The Million Pound Drop. In August 2013, she began presenting ITV's dancing reality series Stepping Out, and in January 2014 began co-hosting Channel 4 reality series The Jump alongside Alex Brooker. The following month she ran, swam and cycled her way across the UK for Sport Relief.

Career: Grimshaw's big break came in July 2012 when it was announced he would be replacing Chris Moyles as host of the Radio 1 Breakfast Show. On TV, Grimshaw has hosted Freshly Squeezed, Style the Nation and The Music Show on Channel 4. In 2013, he filmed cameo roles in EastEnders, Coronation Street, Emmerdale, Hollyoaks and Home and Away. He has appeared as a guest on 8 Out of 10 Cats and Never Mind the Buzzcocks. In 2015, he became a judge on The X Factor.

Career: Ranganathan's breakthrough came in 2013 when he was nominated for Best Newcomer at the 2013 Edinburgh Comedy Awards.
