The pop star was surprised at how "emotional" and difficult she found it to adjust to normal life after she and her bandmate Jules De Martino completed their tour commitments in 2009 and moved to Berlin, Germany, to record their upcoming second album.
She told BANG Showbiz: "We've discovered from being in Berlin that we hate normal life, and that making dinner and doing normal work stuff is really hard for us now.
"For about a month after touring it's so weird because your life has just been sat on a tour bus and planes for two years.
"Then it stops and you find real life, just kind of watching a film and eating dinner, really boring, and you have this huge panic, it's like, 'Oh my god, am I addicted to playing shows every night?' And you kind of get really emotional.
"We've turned into a touring band where you can only function when you're on the road."
Multi-instrumentalist Jules also revealed recording in Berlin - famous for its techno music scene and as the place where David Bowie recorded some of his darkest material - gave their sound a more serious edge.
He explained: "It was hard for us to judge this LP because we're always wrong, we say we have made a more serious record and then people will think it's really uplifting, but I think this album has a dark side to it, more so than the first one."
