Barbarellas (previously known as Ms. Lynch) were an Irish pop duo, consisting of twins Edele and Keavy Lynch (born 15 December 1979), former members of pop girl group B*Witched.

The duo were signed to Ceol Music, and released their debut album Night Mode in 2011.

After B*Witched split, in 2002, Edele worked as a songwriter with the Xenomania production team, co-writing tracks for Girls Aloud and Sugababes, while Keavy established an Irish music production company called Ziiiing.

The duo's debut album Night Mode was released on 17 April 2011 to a mixed reception from critics, and like the singles, did not appear in the Top 100.
