They had seemed to put speculation their marriage was in trouble behind them by the end of 2016, but it appears that 2017 hasn't started off on the best note for Keith Urban and Nicole Kidman.

The couple, who ended 2016 together in Sydney with their daughters after a year spent apart often due to their conflicting work schedules, appeared to be in the middle of an argument while at the Sydney premiere of her movie, Lion, after Kidman's gear up towards Oscar season led her to promote the movie during the vacation-and Urban was not happy about it, frustrating his wife.

"They were meant to meet up in Sydney for a family Christmas, leaving work aside for a couple of weeks and concentrating on themselves for once," a source told The Daily Mail. "Nicole is so sick of Keith constantly sulking. He needs to realize that Nicole's career is important to her, and to start being more supportive. It's very frustrating for her."

The fight comes at the same time that Kidman opened up in an interview with W Magazine, where she admitted that when she tries to call Urban and can't get him to answer the phone, she gets anxious and continues to call him obsessively until he picks up.

"...I know it's terribly demanding, but I don't like it when my husband doesn't answer his phone. I have to keep calling and calling, and I get anxious," she said, "Does that make me high-maintenance?"
