The singer - whose real name is Pippa Brown - was originally due to release the follow-up to her eponymous debut in March, but it has since been shifted back to May.
In an interview with Digital Spy, she explained: "Believe me, it's been a massive pain in my arse. This album has been done for a while now but I guess the record company want it to have the best chance possible.
"I've only just come back to England so I think they want me to do a lot more promo. It's frustrating because I've been mentally prepared for a March release. This album is like a tumour and I just want it out of me now!"
Describing the LP, she revealed: "This one is a little bit darker compared to my last record, which was quite pastel-ey and dancey. This one is a bit rockier too... it's hard to describe it actually! The music has taken on its own personality."
Ladyhawke recently released the music video for her new single 'Black White & Blue', which is officially released this week.
