Less than a year later, Hewitt was married to Australian actress Bec Cartwright with a child on the way.
When Sweden's Bjorn Borg met Romanian tennis player Mariana Simionescu in 1974, he was on-again and off-again with another tennis player, Helena Anliot.
They met in 2000 at the Australian Open after Clijsters' sister requested Hewitt's autograph and were engaged on a boat trip around Sydney Harbor in December of 2003.
Marriage, however, was not in the cards for the two.
Vavrinec moved up through the rankings to become one of the Top 100 by 2000 and earned a spot on Switzerland's Olympic team that year.
It was Simionescu who captured his attention, however, and the two started dating the following year.
Just a month prior to getting married in 1980, Borg and Simionescu took part in a charity mixed doubles match against John Lloyd and Chris Evert-Lloyd dubbed the "Love Match." The married Lloyds won, 6-4, 6-3. While Mirka Vavrinec is most known for being a constant presence by Roger Federer's side and for acting as his manager, she was a former tennis pro as well.
Within months, both of their rankings had improved.
Capriati won the 2001 Australian Open and claimed the No. Showing great chemistry on the court en route to winning the mixed doubles title at Wimbledon in 2007, Jelena Jankovic and Jamie Murray set tongues wagging about whether or that connection was continued off the court.
