Speaking to Daily Mail Australia at Flemington Racecourse, the chiropractor said: "I'm not in a hotel [with Anna] because Monday to Friday I live down here, but she is only here a couple of days."
Tim lives in Melbourne five days a week, where he films the Channel 10 soap Neighbours, while Anna, a lawyer, is based in Sydney.
He also explained that he visited her at her hotel the night before but went back to his house afterwards.
With reference to his lack of wedding ring, he wrote on Instagram earlier this year: "I was never really a ring kind of guy" and added that he only wears it on "special occasions".
Last week, Kyle Sandilands launched a bitter attack on his Trial By Kyle co-star Anna, revealing during an episode of The Project that her marriage to the personal trainer will "never be right".
"This morning, I had her on my radio show, and I said: 'What's the deal with your husband living in Melbourne trying to be an actor on Neighbours?' and she said: 'He's signed for a year'."
After panellist Tommy Little laughed awkwardly, Kyle suggested he knew more about their relationship than he was letting on, implying the seemingly perfect couple's marriage is on the rocks.
"Hmmm... I feel there's trouble there," the 48-year-old continued. "No, no there's no trouble there," he then said, mimicking Anna."Watch that space. Something's going on!"
Kyle slammed the couple the next morning, saying he was, once again, "worried" about their long-term relationship.
"I think that Tim has abandoned her with the move down to Melbourne for Neighbours. She's still living in Sydney, and that worries me. 'He's moved down there permanently and he's left her behind."
After being alerted of his nasty comments, Tim— who rose to fame after handing out roses on The Bachelor and later married Anna in 2018— told the Daily Mail that "Anna and I knuckle down into work during the week and have plenty of quality time on the weekends."
He continued: "We're actually surprised how well we've made the circumstances work. I was getting a little jealous of how much she was saying she loves Kyle but hopefully they just keep that romance in the courtroom."
