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: Campbell cut his broadcasting teeth on Aberdeen's Northsound, joining Radio 1 in 1987 with a late-night Saturday programme. He launched the station's new drive-time slot in 1994, and took over the afternoon show in 1995. He has also branched out into TV, fronting the regional debate programme Central Weekend, which gained notoriety for its raucous arguments, and hosting game show The Wheel of Fortune between 1988 and 1994. Campbell joined Radio Five Live in 1997, and in 2004 he launched daytime chat show Now You're Talking. He hosted Watchdog for eight years until 2009, and now co-hosts Long Lost Family with Davina McCall, and consumer show Your Money Their Tricks.

Career: He initially worked as a house-painter to make ends meet, but acting jobs soon started flooding in, mainly in theatre and TV. He bagged his first leading movie role in the cult film Knightriders in 1981, but it was his performance as John Glenn in the acclaimed The Right Stuff that marked him out as a rising star. In 1995, another fact-based drama about astronauts, Apollo 13, earned him his first Oscar nod. He's been nominated three more times for The Truman Show, Pollock (which he also directed) and The Hours. His other notable films include The Abyss, The Rock, Nixon, A Beautiful Mind, A History of Violence and Man on a Ledge.
