Popstar to Operastar [sic] is a British television programme in which pop stars were trained to sing opera.

As a singing competition, it featured appropriate judges: Mexican tenor Rolando Villazón, Welsh mezzo-soprano Katherine Jenkins and rock singer Meat Loaf, as well as TV home-interiors expert Laurence Llewelyn-Bowen.

Presenters were confirmed as Alan Titchmarsh and Myleene Klass, with the non-operatic Dies Irae from Verdi's Requiem as the theme tune.

The first episode of series 2 brought in 5.98 million viewers, bringing the show its highest ratings to date.

Each week the results show featured a guest performance, normally an opera star singing to promote their upcoming album.

After series 1, it was confirmed Loaf and Llewelyn-Bowen would not be returning as judges and would be replaced by Vanessa-Mae and Simon Callow.
