They're the ruling pop-rock phenomena in Australia, and now they're set to take over the UK too.
They're easy to tell apart in their new video - Jess is the blonde one and Lisa's a brunette. Watch them show how a proper house party is thrown - complete with crazy dancing, guitar smashing and plenty of hands in the air.
The irresistebly catchy 4Ever is the new single from the duo's second album Hook Me Up, out in the UK on October 5th.
