Miriam Nervo and Olivia Nervo (born February 18, 1987) are Australian musicians and songwriters, better known by their stage name NERVO. After signing with Sony/ATV Music Publishing at 18 years of age, the twins pursued careers as songwriting partners, co-writing the Grammy Award-winning single, "When Love Takes Over", performed by David Guetta and Kelly Rowland.

When the sisters were sixteen years of age, a modeling agency indicated an interest in the pair, but Liv Nervo stated in April 2012 that music "was always the focus" for them. The twins were accepted into the Opera Australia Academy, but decided to pursue a music career instead. A contract was then signed with Sony/ATV Music Publishing and the duo subsequently embarked on a songwriting career. Initial recognition for the pair occurred following the single, "Negotiate with Love", written for British pop singer, Rachel Stevens, which reached tenth position in the United Kingdom (UK) music charts in 2005. Also in 2005, the duo released the single "Boobjob" which received substantial airplay in their native Australia. The duo went on to write for Kesha, Richard Grey, Sophie Ellis-Bextor, Ashley Tisdale and the Pussycat Dolls.

When their publishing deal was set to expire they considered dropping their songwriting career due to a dissatisfaction with the modest level of success they had experienced while with the major publisher. Instead they were persuaded to give it another chance by signing with small independent Swedish publisher Razor Boy in 2008. The move reaped quick rewards when the new publisher arranged a writing session with Kelly Rowland through Universal A&R Max Gousse. The group co-wrote Guetta and Rowland's number one dance hit, "When Love Takes Over" which went on to win a Grammy Award, in addition to reaching the top position on numerous charts around the world. The song was also ranked the #1 dance pop collaboration of all time by Billboard.
