Monica Seles is all set to marry 72-year old billionaire Thomas Golisano, according to reports.
Seles, 40 and Golisano have been dating for five years and are living together in Florida. Golisano is a philanthropist and a former National Hockey League team owner. He made his fortunes through Paychex, one of the largest payroll companies in the US.
He is keen on bidding for the Buffalo Bills National Football League (NFL) team, which is up for sale following the death of former owner Ralph Wilson.
Golisano has been married three times and runs the Golisano foundation, which supports programs for people with intellectual disabilities.
Seles is the youngest player to win the French Open when she was just 16 in 1990. She has won 9 Grand Slams in her career.
Seles had to break from professional tennis for two years, after a mentally-ill fan of Steffi Graf stabbed her during a tennis match in Germany.
Seles announced her official retirement from the game in 2008.
