Wedding bells may soon be ringing for tennis great Monica Seles.

The former No. 1 and Hall of Fame star is reportedly tying the knot with her long-term boyfriend of over four years. According to the New York Daily News, Seles is engaged to Tom Golisano who she has been dating since 2009.

Golisano made the announcement during an appearance at an upstate New York high school last Thursday. No official wedding date has been announced. This would be the first marriage for Seles.

Golisano, 72, is a billionaire executive who also made three unsuccessful bids for New York governor in 1994, 1998, and 2002.

Seles, 40, is the winner of nine Grand Slam singles titles. She retired from the sport in 2008 and was later inducted into the International Tennis Hall of Fame in 2009. Since retiring, Seles released an autobiography and also appeared as a contestant on "Dancing With The Stars".
