Fergie has become a judge for an online singing and songwriting search.

The Black Eyed Peas star will head up the panel alongside songwriting legend Diane Warren, Natasha Bedingfield and Delta Goodrem for 'Avon Voices', a competition run by beauty firm Avon which will give the winner a chance to record a professionally produced album.

Anna Segatti, Group Vice President, Avon Western Europe and Middle East, said: "In Celebration of Avon's 125th anniversary in 2011, we are inviting people from around the world to come together and showcase their talents. For generations Avon has been empowering women to find their individual voices, tell their stories and share their dreams. Now we are asking women to find their singing voices.

"We are thrilled to have music industry legends on board to join us in the hunt for the UK's next Big Star. If you're an avid singer or songwriter now is really your time to shine and be in with an opportunity to win this once in a lifetime chance with Avon Voices."

To have a chance of winning, applicants from around the world simply need upload a demo video of themselves - via avonvoices.co.uk in the UK - and the 'Avon Voices' celebrity panel will announce the 200 first round global contenders on International Women's Day (08.11.10).
