Budapest - Hungarian Olympic champion and multiple world record holder Katinka Hosszu said on Thursday that she was no longer working with her US coach and husband Shane Tusup citing "personal issues".
"I would like to get ahead of the gossips, sadly Shane and I haven't been able to resolve our personal issues, therefore we are no longer working together," Hosszu, 29, said in a Facebook post.
"I am still preparing for the upcoming competitions while looking at my options for my support team," she added.
Last December Hosszu said that their relationship was "undergoing trials," and attended separately a Hungarian sports gala where Tusup pledged that he "would work to change".
Nicknamed the "Iron Lady" and currently Hungary's most successful sports star, Hosszu met Tusup, 30, when both were swimming at the University of Southern California.
The American took over as her coach soon after a disastrous London Olympic Games in which she missed out on podium finishes despite high expectations.
With Tusup as her coach, Hosszu became one of the world's top swimmers, winning three golds and a silver at the Rio Games.
She also won two golds each at World Championships in 2013, 2015, and 2017. Her next major target is the 2020 Olympic Games in Tokyo, she told Hungarian media earlier this year.
Tusup's intensive training methods for Hosszu raised eyebrows among some swimming insiders, but his emotional reactions to her races also won admirers.
NBC's official Olympics Twitter account in 2016 urged women to "find someone who loves you the way Katinka Hosszu's husband loves her".
