Johnny Weir’s recent separation from husband Victor Voronov may have been caused by botched vacation plans, according to a report.

On Wednesday, the 29-year-old former Olympic figure skater took to Twitter to announce that he and Voronov had split after two years of marriage. “It is with great sadness that I announce that my husband and I are no longer together,” Weir tweeted. “My heart hurts, and I wish him well.”

Weir’s post gave no indication as to the cause of the separation, but sources close to the couple claim that his busy professional schedule was a major source of strain on their marriage, TMZ reports. The sources said that Weir and Voronov planned to sort through their issues by taking a vacation together.

However, when Weir was chosen to co-host NBC’s coverage of Winter Olympic figure skating in February, the couple was forced to postpone their vacation indefinitely. Weir’s schedule prevented him from seeing Voronov more than “two or three times” in the past month.

Eventually, the sources add, Voronov gave Weir an ultimatum regarding their pending vacation plans, but Weir’s career prevented him from taking an extended break and ultimately led to the split.

In the months before they announced their plans to divorce, Weir and Voronov’s relationship had grown increasingly tenuous. Earlier this month, Radar Online reported that the pair was involved in a domestic dispute about a month before the Winter Olympics.

According to the report, Voronov filed a police report in which he accused Weir of biting him. However, they ultimately asked a N.J. judge to dismiss the case.
