The singer, whose self-titled debut was released in 2008, confessed that she felt 'weighed down' by the pressure to live up to her previous effort.
"It’s been really weighing me down," she told Stuff. "It’s that second album thing, people always talk about it and it’s true.
"It is really stressful and I just keep thinking people are going to want to hear a 'Paris is Burning' or 'My Delirium' but I'm not going to have those songs, it’s going to be a completely different album and style."
Discussing her forthcoming LP's sound, she said: "It's still pop, it’s just a bit darker and a bit rockier. I guess I'm just playing a lot more guitar and having a lot more fun in the guitar-sense.
"I'm making an album that’s making me really excited but you never can tell if it’s going to make other people excited too."
Ladyhawke peaked at number 16 in the UK and sold over 100,000 copies.
