Pregnant pop star Fergie has turned to acupuncture to cope with morning sickness.

The Black Eyed Peas star and her actor husband Josh Duhamel are expecting their first child later this year (13), and the singer reveals she is using alternative remedies to minimise her nausea.

During an appearance on U.S. breakfast show Good Morning America on Thursday (21Mar13), she said, "I've been doing acupuncture, which really helps with that (morning sickness), and Chinese herbs."

And although Fergie insists she can't wait to be a mum, she feels a little unprepared, admitting, "I have no idea what I'm doing. No idea... I'm just going to play it by ear and see how things go and let the natural instincts kick in."
