Nicole & Keith UNDER PRESSURE

The pair raised eyebrows over their unusual behaviour at the Oscars amid security fears

Nicole Kidman and Keith Urban's public displays of affection at the Oscars raised eyebrows from fans N and fellow celebs, but an insider says the stressed pair were just keen to let off some steam, after what has been an incredibly worrying few months.

The A-list couple are growing increasingly concerned about their family's safety and are splashing the cash on upping the security at their sprawling Australian estate in the NSW Southern Highlands.

The stars, both 55, have scored approval to add a $32,000 gatehouse, which will be manned by round-the-clock security guards at their $6.5 million Bunya Hill farm in Sutton Forest.

"It is sad that they have to go to such lengths to protect their family," commented one fan. "I hate that they have to do that - but children need a safe and secure home - bravo to them for putting family as a priority," added another.

SPOOKED BY STALKERS
Nicole - who shares daughters Sunday, 14, and Faith, 12, with Keith - is right to be wary. For decades, the Aussie actress has been targeted by stalkers. In 2001, Nic was forced to file a restraining order against an alleged stalker who turned up at her Hollywood home.
