Black Eyed Peas got drunk recording their new album.

The group wanted to get in the party spirit while recording tracks for 'The E.N.D.' in particular on a track called 'Out of My Head'- which features Fergie opening with the words "I'm so tipsy" - they decided to consume alcohol before beginning work.

Fergie said: "The song reminded me of the fun character of 'My Humps.' I told Will we have to get some wine if I'm going to do this correctly. I'm not going to front on this song. So we all got a little tipsy."

The group love being in the studio together, likening their output to that of faed pop artist Andy Warhol.

Fergie added to Billboard magazine: "There's always a sense of Andy Warhol whenever we make a Black Eyed Peas album. It's an artistic factory with several rooms going at the same time. We don't just sit down. We jump from room to room, all of us adding ideas to the recipe. If you get burnt out on one idea or your ears get tired, you walk to another room and step into a whole fresh creative zone for more ideas."
