Fergie has revealed she’s prepared to work constantly - even foregoing sleep sometimes - to ensure her continued pop success.

After rising to fame in the Black Eyed Peas, Fergie released her first solo album (’The Dutchess’) earlier this year but after working hard to produce and promote the album, doesn’t have any plans to relax.

She said recently: “You can’t assume any success.”

“Usually artists spend time in the studio recording an album, then they do prep, then they do press. And then they tour.

“Most find it hard but I love it. I even get up at three in the morning sometimes to work.”
