Hingis, wanting to concentrate on doubles, no longer coaching Lisicki
"Martina and I have parted ways on a mutual agreement. After winning the doubles title in Miami she found the desire to play doubles again," said Lisicki on Facebook.
Lisicki, who reached the Wimbledon singles final a year ago, will once again be coached by her father.
Lisicki said that she and Hingis, who won Miami together, might still be "playing doubles together here and there."
Hingis received a wild card into the Wimbledon doubles with Vera Zvonareva.
