The announcement coincides with the 15th anniversary of the WTA's participation at the Dubai Duty Free Tennis Championships, which is currently underway in Dubai.
During their time as global brand ambassadors, Ivanovic and Wozniacki have represented Dubai Duty Free at a number of prestigious international events, most recently this December, when both Ivanovic and Wozniacki attended the Dubai International Film Festival.
Additionally, Wozniacki was at the Newbury Races for the Dubai Duty Free-sponsored spring meeting in 2012 and the Dubai Airshow Gala the following year, while Ivanovic made an appearance at the Dubai Duty Free Irish Derby in 2013, and walked the red carpet at the 2012 Dubai International Film Festival. In 2015, Ivanovic and Wozniacki will take fans "Behind the Ropes" in a new series that provides an exclusive, inside look at life on the WTA.
"For as long as I can remember, Dubai Duty Free has been one of the biggest supporters of women's tennis," World No.6 Ivanovic said. "I am thrilled to continue my partnership with such a wonderful brand - we are now in our fourth year together. As part of my role as an ambassador for DDF I've taken part in some fun activities and learnt a lot more about the culture of the region. I'm very happy to renew our partnership, and to be back here competing for the Dubai Duty Free Tennis Championships title."
"It is an honor to represent Dubai Duty Free, the world's leading duty free retailer, as a brand ambassador," added World No.5 Wozniacki. "I like to enjoy and explore each city that I travel to and I've had the opportunity to learn about the culture and experience some amazing events as an ambassador. And, I love playing at the Dubai Duty Free Tennis Championships. I've always played well at this tournament and coming back here, having won in the past, brings back so many great memories for me."
Colm McLoughlin, Executive Vice Chairman of Dubai Duty Free, said: "Caroline and Ana are both supreme professionals and are excellent ambassadors both for women's tennis and for Dubai Duty Free. They have provided an exciting addition to many prestigious international events such as the Newbury Races, the Dubai Airshow Gala, the Dubai Duty Free Irish Derby and the Dubai International Film Festival, which is sponsored by Dubai Duty Free.
"In addition, the pair have been featured in Dubai Duty Free's Full Of Surprises Travel Show. We are delighted to have them continue as our brand ambassadors and look forward to continuing to work with them on our ambassador program in the coming year."
"Dubai Duty Free has been a loyal partner and a great ambassador for women's tennis in the Middle East and around the globe," said Stacey Allaster, Chairman & CEO of the WTA. "We appreciate their commitment to equal prize money, their vision for the sport, and I know Ana and Caroline will be outstanding ambassadors for not only Dubai Duty Free but women's tennis too."
A sponsor since 2004, Dubai Duty Free's partnership with the WTA has been marked by leadership and innovation. The Player Ambassador Program is just one element of the partnership between Dubai Duty Free as the No.1 duty free retailer in the with the No.1 global sport for women.
For the last three years, Dubai Duty Free has been the presenting sponsor of the WTA's prestigious year-end World No.1 awards, and the annual pre-Wimbledon party. In addition fans have been able to enjoy an insight into the WTA players and city stops on the tour through Dubai Duty Free's Full Of Surprises Travel Show.
Dubai Duty Free, in its role as owner, organizer and title sponsor of the Dubai Duty Free Tennis Championships, was the first event in the Middle East to award equal prize money and is a longtime supporter of the growth of women's tennis throughout the region. In 2013, the event received the Gold Award for Event Marketing at the seventh ISEM Awards held in London.
This year's Dubai Duty Free Tennis Championships began on Sunday and boasts a field that includes seven of the world's Top 10, as well as four former World No.1s and four former champions of the event.
