Queensberry was an all-female German pop group founded in late 2008. Formed during the seventh season of the television talent show Popstars, Popstars – Just 4 Girls, the original line-up consisted of singers Leonore Bartsch (Leo), Gabriella De Almeida Rinne (Gabby), Antonella Trapani (Anto), and Victoria Ulbrich (Vici). In July 2010, it was announced that both Antonella and Victoria had left the group, to be replaced by new members, Selina Herrero and Ronja Hilbig.

Volume I is the debut studio album by German girl group Queensberry. Released by Starwatch Music, Cheyenne Records, and Warner Music on 12 December 2008 in German-speaking Europe, a week prior to the announcement of the fourth member of quartet line-up on the show's finale, the album produced three versions, each featuring a different Popstars – Just 4 Girls contestant competing to become part of the Queensberry group, including Katharina "KayKay" Kobert, Patricia Ivanauskas or eventual band member Antonella Trapani.
