question:
(CNN) -- Martina Hingis and Anna Kournikova will team up again to play at this year's Wimbledon championships. The popular pair won the 1999 and 2002 Australian Open doubles titles, but will be returning the SW19 to play in the legends doubles event for players who are retired from the professional circuit, the management company Octagon said Tuesday. Swiss star Hingis won five grand slam singles crowns and nine in doubles during a glittering career which ended under a cloud in 2007, when she was suspended for two years for testing positive for cocaine at Wimbledon. The 29-year-old denied taking the drug, but did not appeal the ban, which ended last September, prompting speculation that she may attempt a return to the WTA circuit.Martina Hingis and Anna Kournikova to be re-united at Wimbledon this yearThe pair will play in the legends doubles event at SW19Hingis has ended a two-year ban after testing positive for cocaine at 2007 Wimbledon
