Nicole Kidman stole in the show at the Academy of Country Music Awards in Las Vegas – and, unusually, she did it by covering up.

The actress joined singer husband Keith Urban on the red carpet clad neck-to-toe in a body-hugging black sequinned gown that showcased her stunning figure to eye-popping affect.

It was just a shame that her dress – which was backless and split up the back to reveal her toned pins – resembled a shiny straight jacket.

Miley Cyrus also put in an appearance at Sunday's event, as did LeAnne Rimes, who braved the gossip about her alleged extra-marital affair.
