Keith Urban and Nicole Kidman got involved in a confrontation with a fellow opera patron in January.
The couple was at a performance of The Merry Widow at the Sydney Opera House. At the end of the show, they stood to give the performance a standing ovation and that upset the man behind them. Apparently it's against opera protocal to do that, so the man hit Nicole with a program instead of explaining the rule to them. That made Keith angry, so he ended up getting into a verbal altercation with the man. Eventually Keith's security team removed the couple and Nicole's mom, who had gone with them. Keith says he tried to deal with the man fairly, rather than getting crazy.
