Ana Ivanovic has been added to a star-studded field for the 2016 ASB Classic in Auckland.
The Serbian joins fellow headline acts Venus Williams and Caroline Wozniacki, a line-up tournament director Karl Budge didn't think was possible.
"It's amazing. Three former world number ones, three grand slam champions and two former winners in one year is an incredible result," said Budge.
"Having Ana join Venus and Caroline was something we never thought was possible.
"The crowds can expect to be wowed by some great on court battles, as well as a good dose of glamour."
Other notable players include two-time Grand Slam Champion Svetlana Kuznetsova and rising American star Sloane Stephens.
