Quick-thinking BLACK EYED PEAS star Fergie once squirted champagne all over herself to disguise the fact she'd wet herself during a concert.

The LET'S GET IT STARTED singer was red-faced when she realised she wouldn't be able to hold her water onstage at one of her first Black Eyed Peas shows in Australia.

She recalls, "I had a few drinks before the show, but I didn't think to go to the restroom before we went onstage.

"We were jumping around - it was all very rock 'n' roll - and my bladder just started... you know.

"Somebody brought out these champagne bottles because it was the New Year, and I basically opened one up and squirted it all over myself, so nobody would notice.

"It was a very memorable Pea experience."
