Hungarian triple Olympic gold medalist swimmer Katinka Hosszu announced Thursday that she is parting ways, at least professionally, with her husband and coach Shane Tusup.

The two began to turn heads with their unconventional partnership at the 2016 Olympics, and since then, aspects of their public life have led fans to question what might be going on behind-the-scenes.

Hosszu historically has competed in an exceptional number of races, and became the first swimmer in history – male or female – to rack up over $1 million in prize money alone, earning her the nickname of “Iron Lady.” Tusup is known for his overt temper flares, a recent one of which occurred at a youth swim meet. Together, the two founded Iron Aquatics, a Hungary-based swim team.

Culmination of rocky months

The pair announced in December 2017 that their relationship was under duress, and Hosszu filed for divorce in February. Despite the tumultuous late 2017 and early 2018, it had appeared on social media recently that the couple might have reconciled.

However, Thursday, Tusup alleged in a press release that Hosszu “betrayed” him by committing infidelity multiple times with one of her training partners, Daniel Dudas.

“At the end of November, I was completely blindsided by the sudden overnight strain on our marriage, and any hope to reconcile the marriage was completely sabotaged by Katinka continuously misleading me into believing the issues were all me and my character,” Tusup wrote. “As I look back on our ten years together, I question whether her commitment to me was real.”

Hosszu released her own statement on her Facebook account, which has since been deactivated, but swimming news site SwimSwam captured it while it was still live:

Hosszu, one of the biggest names in swimming over the past few years, is scheduled to compete at the 2018 Speedo Grand Challenge in Irvine, California, on Friday.
