Jonathan Stephen Ross, OBE (born 17 November 1960) is an English television and radio presenter, best known for presenting the BBC One chat show Friday Night with Jonathan Ross from 2001 until he left the BBC in 2010. Ross began hosting a new chat show on ITV1 starting 3 September 2011. Ross also hosted his own radio show on BBC Radio 2, and acted as a film critic and presenter of the Film programme.

Ross began his television career as a programme researcher, before débuting as a television presenter for The Last Resort with Jonathan Ross on Channel 4 in 1987. Over the next decade he had several radio and television roles, many through his own production company, Channel X. In 1995 he sold his stake in Channel X, and embarked on a career with the BBC. In 1999, Ross took over presenting the Film programme from Barry Norman, and also began presenting his own radio show, while two years later he began hosting Friday Night with Jonathan Ross. For the chat show, Ross won three British Academy of Film and Television Arts (BAFTA) awards for Best Entertainment Performance, in 2004, 2006 and 2007. By 2006 Ross was believed to be the BBC's highest paid star. In 2005, Ross was made an Officer of the Order of the British Empire (OBE) for services to broadcasting. Ross has been involved in controversies throughout his broadcasting career. As a result, in 2008 he wrote a semi-autobiographical work titled Why Do I Say These Things?, detailing some of his life experiences.

Anthony McPartlin (born 18 November 1975) and Declan Donnelly (born 25 September 1975), known collectively as Ant & Dec, are an English comedy and TV presenting duo from Newcastle upon Tyne, England. The duo first rose to fame as actors on the children's television show Byker Grove, during which and in their subsequent pop career they were respectively known as PJ & Duncan – the names of the characters they played on the show. Since then, Ant & Dec have had a very successful career as TV presenters, presenting shows such as SMTV Live, Friends Like These, Pop Idol, Ant & Dec's Saturday Night Takeaway, I'm a Celebrity...Get Me Out of Here!, PokerFace, Push the Button, Britain's Got Talent, Red or Black? and Text Santa. They have also returned to acting, starring in a 2002 Tribute to The Likely Lads and the 2006 film Alien Autopsy.

Ant is the taller of the two at 5'8" (1.73 m) and Dec is two inches shorter at 5'6" (1.68 m). It is a running joke that many people do not know who is Ant and who is Dec, even though their appearances differ significantly. To assist with identification, they follow the 180 degree rule; all their TV appearances and publicity photos have Ant on the left and Dec on the right, but even this does not help everyone.
