The Saturdays are an English-Irish girl group based in London, England. The group formed during the summer of 2007 and has been on hiatus since 2014. The lineup consists of Frankie Bridge, Una Healy, Rochelle Humes, Mollie King, and Vanessa White. They were formed through Fascination Records, a sub-division of Polydor Records, which gave them an instant record deal with the label. As soon as the contract was finalized, the Saturdays went on tour with Girls Aloud during their Tangled Up Tour. The group's music style is pop, but throughout their career, their management has experimented with dance-pop and electropop. Songwriters and producers Ina Wroldsen, Steve Mac, Camille Purcell, and Quiz & Larossi have helped create their music. In July 2008, The Saturdays released their debut single and first Top Ten hit, "If This Is Love". Their debut album, Chasing Lights, released the same year, charted at number nine on the UK Albums Chart; it was certified platinum by the BPI and produced three more top ten singles: "Up", "Issues", and "Just Can't Get Enough". "Work" was also released from the album. The group's first concert tour, The Work Tour, took place in 2009. The group's second album, Wordshaker, produced the Top Ten hits "Forever Is Over" and "Ego". In 2010, the Saturdays released a mini album, Headlines!, which contained the top 10 hits "Missing You" and "Higher", the latter of which featured guest vocals from Flo Rida. The mini-album was supported by the group's second concert tour, The Headlines Tour. Their third album, On Your Radar, was released in 2011 and resulted in two top 10 singles: "Notorious" and "All Fired Up".

A girl group is a music act featuring several female singers who generally harmonize together. The term "girl group" is also used in a narrower sense in the United States to denote the wave of American female pop music singing groups, many of whom were influenced by doo-wop and which flourished in the late 1950s and early 1960s between the decline of early rock and roll and start of the British Invasion. All-female bands, in which members also play instruments, are usually considered a separate phenomenon. These groups are sometimes called "girl bands" to differentiate, although this terminology is not universally followed.
