Four more singers will be joining Australia's version of "The Voice."

Singers Megan Washington, Darren Hayes, Ricki-Lee Coulter and Benji Madden will be the new mentors for Channel Nine's upcoming singing talent show.

Last month, the network revealed the judges/coaches of the show that includes Keith Urban, Joel Madden, Seal and Delta Goodrem. Each mentor will be teamed up with a judge/coach.

Ricki-Lee Coulter will be working with soul singer Seal; Megan Washington will team up with Nicole Kidman's better half Keith Urban; longtime friends Delta Goodrem and Darren Hayes will be working together and the Good Charlotte twins Joel and Benji Madden will belong to the same group.

Ricki-Lee Coulter told The Daily Telegraph that she has "friends who have sung in my band and have now auditioned for the show - so they are going to get the shock of their lives."

Seal and Coutler have not met yet. However, the soul hitmaker said that "he wanted someone who knows everything there is about the market here" and she knows the industry well because she has been in it for eight years.

A lot of Australian television networks are targeting Darren Hayes. The former front man of Savage Garden was offered by Channel 10 for a judging role on the new look Young Talent Time but he declined the opportunity to work with Channel Nine for "The Voice."

Hayes said that other music reality shows "disappoint" him, because he believes the contestants "have this assumption that fame will make them instantly rich and there's no guarantee of that".

"The Voice" is currently filming in Sydney and will be hosted by Darren McMullen. The show will have its pilot sometime after Easter.

Channel Nine hopes that the new show will be a big hit and will shoot up the ratings of the network. Watch the promo of "The Voice" featuring the four coaches/judges of the new show.
