Martina Hingis is a serial adulterer, claims estranged husband

The estranged husband of tennis star Martina Hingis has broken his silence over their marriage and accused her of being a serial adulterer.

French equestrian Thibault Hutin, 26, claimed he walked in on his wife with another man a year after their wedding and after he forgave her she cheated on him again.

The revelations come at a particularly sensitive time as Hingis, 32, who shot to fame as the youngest female world No 1 aged just 16, is due to be inducted into the International Tennis Hall of Fame this weekend at a ceremony in Newport, Rhode Island.

Mr Hutin told Swiss newspaper SonntagsBlick: “A year after the wedding [...] we were supposed to meet in New York and I wanted to giver her a surprise.

“Upon arriving at the hotel room it was me that was surprised, because Martina was not alone.”

Hutin said he tried to salvage the marriage but “late last year I found out that she had cheated on me again”.

He said: “Martina has a very personal conception of morality. She has always been like that; I think she has always been unfaithful to her boyfriends.”

He added: “She is not alone in the tennis world, which I now know quite well. But I thought she was different from the others, that she really loved me.”

Hingis had only just broken off her engagement to Swiss attorney Andreas Bieri when she met Hutin at a show-jumping competition in St. Tropez in April 2010.

The pair were married after a whirlwind romance.

The devastated husband said he was not even aware they had officially split until Hingis made a statement saying the pair had been separated since the beginning of the year to Swiss magazine Schweizer Illustrierten on Monday.

Hingis is now reported to be in a relationship with David Tosas Ros, a Spanish sports management executive. The pair were spotted sitting together at Roland Garros.

Hutin said: “They shared the hotel room there and they paraded themselves in public at the in the Bois de Boulogne. There are even pictures of them. You can imagine how painful it was for me.”

Former child prodigy Hingis was the world’s best player for 209 weeks, winning three consecutive Australian Opens, one Wimbledon title and one U.S. Open between 1997 and 1999.

She also held the world number one doubles ranking for 35 weeks, making her one of just five women in history to have been the world number one in singles and doubles simultaneously.

After an early retirement due to injury in 2002 at the age of 22, Hingis made a return to tennis in 2006 but quit a year later after testing positive for cocaine in a routine drug test.

She denied using the drug but opted not to contest the ban imposed by the International Tennis Federation.

She has not commented about Mr Hutin’s claims.
