Martina Navratilova, 59, proposed Saturday to her longtime girlfriend Julia Lemigova in a very big way — popping the question in front of the U.S. Open crowd via the Jumbotron at Arthur Ashe Stadium in Flushing, New York.

As her Tennis Channel boss, Ken Solomon, was interviewing her, Navratilova turned toward her girlfriend and said that she had her own question she needed to ask, according to People.

The Tennis Channel commentator then got down on one knee and presented her girlfriend with an engagement ring, according to New York Daily News.

After asking the important question, Lemigova said, “Yes!”

The newly engaged couple then opened a bottle of Moët & Chandon Brut Imperial champagne to celebrate their engagement and future together.

“I have been waiting for the right time to ask Julia to marry me,” said the newly engaged, 18-time grand-slam-winning champion. “I thought this was the right place and the right time to pop the question, and thankfully I got a yes.”
