Retired tennis champion Martina Navratilova proposed to her long term girlfriend during a US Open tennis game.

The 57 year-old sports legend, who was once called “the greatest singles, doubles and mixed doubles player who’s ever lived” by Billie Jean King, proposed to her partner Julia Lemigova at the semi-final match between Kei Nishikori and Novak Djokovic at Arthur Ashe Stadium in New York.

The proposal was shown on-screen at the stadium, and Navratilova told the spectators, “I have been waiting for the right time to ask Julia to marry me.

“I thought this was the right place and the right time to pop the question and thankfully I got a ‘yes’.”

She later told press that “it was kind of an out-of-body experience” adding, “you’ve seen people propose at sporting events before, in movies, in real life and here it was happening to me. It was like I was watching myself do it.”

She then took to Twitter to thank fans for all their support.

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