Career: In 1987, Ross and his friend Alan Marke devised a format inspired by Late Night with David Letterman, and after struggling to find a suitable host, Ross stepped in. The resulting show, The Last Resort with Jonathan Ross, made him a star. Other major projects include his chat shows Friday Night with Jonathan Ross and The Jonathan Ross Show, and his stint as the reviewer of the BBC's Film programme. He's also a massive comic book fan; his first foray into the genre, Turf, was published in 2010. But he's also hit the headlines for various controversies over the years, including the notorious Sachsgate, which involved a prank call made by him and Russell Brand to actor Andrew Sachs in 2008.

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.
