After long absences from tennis, Kournikova and Hingis will play together in the legends' doubles event at the All England Club this year, the Octagon agency said Tuesday.
Five-time major champion Hingis, 29, retired for the second time in 2007, when she was given a two-year suspension for testing positive for cocaine after a match at Wimbledon. She denied taking the drug but did not appeal the ban, which ended on Sept. 30, 2009.
The 28-year-old Kournikova hasn't been a regular on tour since 2003. She was a Wimbledon semifinalist in 1997.
They won two Grand Slam doubles titles together, at the Australian Open in 1999 and 2002.
