Moody Nicole Kidman Smashes Plates In At-Home ‘Rage Room’

Angry Aussie Nicole Kidman’s explosive temper has gotten so bad husband Keith Urban

had a “rage room” installed in their Nashville, Tenn., home —

and sources said the new addition has helped save their troubled marriage!

Keith quickly arranged for the “Big Little Lies” star to have her own rage room after hearing how therapeutic they can be —

because he was sick of his wife unleashing her anger on HIM!

When her rage erupts, Nicole can choose from several baseball bats — wood or metal — for smashing things to bits.

And the rage room frequently gets restocked to give her new objects to destroy.

“Keith is always going to charity stores to buy stuff he knows Nic will want to attack.

The other day, Keith picked up a couple of books about ex-hubby Tom Cruise —

which she gleefully ripped to shreds,” snitched our mole.
