Martina Hingis` estranged hubby accuses her of being serial adulterer

Washington: Tennis ace Martina Hingis` estranged husband, Thibault Hutin , has accused her of being a serial adulterer, insisting that she cheated on him several times during their two year marriage.

Late last week, the French equestrian told a Swiss publication, SonntagsBlick, that a year after the wedding, the couple was supposed to meet in New York and he had wanted to give her a surprise, the Huffington Post reported.

Hutin said that upon arriving at the hotel room, it was him that was surprised, because the sports star, who retired from the sport in 2007, was not alone.

He asserted that Hingis has a very personal conception of morality and she has always been like that.

Hutin said that in his opinion, Hingis has always been unfaithful to her boyfriends.

The pair allegedly broke-up earlier in 2012, though Hutin claimed he only recently found out about their separation.

The duo tied the knot in December 2010 after a whirlwind romance.
