To die for, indeed!

Nicole Kidman was back in bombshell mode on the New Orleans set of her new flick The Paperboy.

The 44-year-old mother of four and natural redhead has gone bleach blonde (likely wearing a wig) for the sexy role (Zac Efron costars).

On Wednesday, the Oscar winner was snapped on set looking like Old Hollywood screen goddess with heavy makeup, wearing a short, short skirt, untucked men's shirt and white stilettos that showed off her killer legs.

How does sexier-than-ever Kidman (married to Keith Urban) feel about being past the big 4-0?

"Yippee! I can't believe I made it," the Just Go With It star has said. "I'm so fine with it. People want you to have some sort of breakdown, but I'm relieved, and I've lived a life."

Kidman has two daughters -- Sunday Rose, 3, and Faith Margaret, 8 months -- with hubby of 5 years Urban. She and ex-husband Tom Cruise have son Conor, 16, and daughter Isabella, 20.
