The veteran chat show host returns, inviting more celebrity guests to take a seat in his famous green room, before subjecting them to his unique form of no-holds-barred questioning. This year, he begins by welcoming Oscar-winning actress Renee Zellweger and Grey's Anatomy heart-throb Patrick Dempsey to the studio. The pair are starring together in the latest Bridget Jones film, Bridget Jones's Baby, in which the unlucky-in-love Londoner finds herself back on the singles market - just in time to discover she's expecting. Also making an appearance are actor, director and producer John Malkovich, actress and comedienne Aisling Bea, and a selection of Team GB's Olympic heroes, namely the women's hockey team, and cyclist couple Laura Trott and Jason Kenny. Plus, Brit Award-winning singer-songwriter Tom Odell performs live.
