In June and July 2008, over 2,300 hopefuls turned up to open auditions in Dortmund, Dresden, Hamburg and Rust which required both singing and dancing experience.

[9] After numerous elimination rounds, sixteen candidates flew to Sharm El Sheik, Egypt, where they intensified their training in singing, dancing, and fitness.

Fourth member, Swiss-born, German-Italian, Antonella, was not announced until 18 December, when the show was resumed, based on her having sold most of her version of the group's debut album Volume I (which had been released in three different versions, a week prior to the finale, and featuring one finalist each) and her winning a public televoting over fellow campaigners Patricia Ivanauskas and Katharina Kobert (KayKay).

[11] Ironically, although each of the Queensberry girls had already performed together with all of their future bandmates (varying from duets to quartets), at some point throughout the season, it had never happened that all four of them made up one working group together.

[11] In January 2009, the album Volume I was certified gold by the IFPI,[3] and in February, the band released their first main single, a double A-single consisting of the ballad I Can't Stop Feeling and their promotional song No Smoke - a cover version of the 2008 record by Canadian Idol winner Eva Avila.

[12] On 18 June 2010, the girls released two new songs as the soundtrack for the Hanni und Nanni movie, while their record contract with Warner Music in Germany was discontinued.

[13] Selina Herrero,[2] a German-Spanish singer from Bad Kreuznach in Germany, who first hit the German single charts in 2008 with Don't Be Shy and You Can't Stop Me, and Ronja Hilbig, a singer from Hamburg, who had played the role of Nala in the German version of the musical The Lion King and had been a member of Die Lollipops,[2][14] were brought in as new members.

In October 2010, the group recorded its earlier single I Can't Stop Feeling in Spanish as Yo No Puedo Vivir Sin Ti.

The song, written by Teemu Brunila and Kid Crazy, and adapted for Spanish by José Valdes, was first performed on VIVA Live.

[15] The girls guest star on the album of German rapper Kitty Kat, and featured on a single called "No Time for Suckers".
