The hook-filled, rocking pop of the Veronicas comes from Brisbane, Australia's Jess and Lisa Origliasso, twin sisters who have been working in show business since they were five years old. Born on Christmas Day, Jess and Lisa were first known simply as the Origliasso Twins. Singing at events and award shows made the young twins comfortable in front of an audience and drew the attention of agents and talent agencies. In their teens, the twins released three teen pop albums as Lisa & Jessica.
In 2001 the girls landed recurring roles in the Australian children's series Cybergirl. Songwriting was already playing an important role in the sister's lives and their style was changing from teen pop to teen rock. They became Teal and released the single "Baby It's Over," a hooky number that made the twins sought-after songwriters. American Idol's down under cousin, Australian Idol, employed the twins and one of the Origliassos' compositions appeared on Australian Idol winner Casey Donovan's 2004 debut album, For You, while another of their tracks landed on Japanese pop singer Miz's album Say It's Forever the same year. The girls were now entirely focused on becoming an internationally successful band and were traveling the globe to shop their demos and collaborate with veteran hitmakers. They moved to Los Angeles, changed their name to the Veronicas, turned 20 years old, and landed a deal with the Warner Bros.-associated label Sire. Sire released the Veronicas' full-length debut, The Secret Life Of..., in early 2006. A year later they released Hook Me Up. When it was released as a single, the album's title track became the duo's first Australian number one.
