Cyrus told Seventeen magazine that she and Nick Jonas had dated for two years and "were in love", but were "fighting a lot" by the end.[143] After the break-up, Cyrus says that she initially "rebell[ed] against everything Nick wanted me to be. And then I was like, I've got to be by myself for now, and just figure out who I really am."[143] In February 2008, Cyrus and her friend Mandy Jiroux opened a YouTube account and began posting videos of what they called The Miley and Mandy Show. The show, described as a "YouTube hit," is said to be filmed for fun by Cyrus and Jiroux and to be entirely their work, with Cyrus and Jiroux editing the footage together.[144]
