Martina Navratilova still knows how to rise to the occasion at the U.S. Open. This time, she did it by dropping to one knee.

More than 25 years after the tennis legend won her fourth and final single's title in New York, Navratilova surprised her girlfriend, Julia Lemigova, with a proposal. The heartwarming moment was shown on the big screen at Arthur Ashe Stadium on Saturday, reported People.

"I was very nervous," Navratilova said later, via The Associated Press. "It came off. She said yes. It was kind of an out-of-body experience. You've seen people propose at sporting events before, in movies, in real life. Here it was happening to me. It was like I was watching myself do it."

The couple has been together since 2006, according to the Daily Mail. After #shesaidyes, Navratilova took to Twitter to thank her fans for the support.

Thanks everyone for your good wishes- I am very happy, so is Julia and our whole family:)
