Kidman announces engagement

Oscar-winning actress Nicole Kidman has revealed that she is engaged to country music star Keith Urban.

Kidman hosted the 30th Anniversary gala for United Nations organisation UNIFEM in New York City on Saturday, where she was accompanied by Urban.

The Hours star confirmed the engagement to US publication People, admitting Urban was not just her boyfriend, saying “He's actually my fiancé.”

“I wouldn't be bringing my boyfriend (to the event).”

The confirmation of the engagement ends months of speculation about the Australian couple, who were first spotted together last July.

In November, Kidman was photographed wearing a ring on her wedding finger while walking arm-in-arm with Urban in Boston, USA.

The actress, who has been in New York's Hamptons region shooting an as-yet untitled film for director Noah Baumbach, is a goodwill ambassador for UNIFEM, the United Nations Development Fund for Women.

Kidman was previously married to fellow star Tom Cruise. The couple adopted two children together, Isabella (aged 13) and Connor (aged 11).
