Hollywood’s favorite duo are back and hotter than ever.

Paris Hilton and Nicole Richie are bringing back the early aughts, one updo at a time.

The friends were photographed in extravagant gowns while filming a reunion episode of The Simple Life reboot in Beverly Hills, Calif. on Aug. 22.

Hilton, 43, wore a matte black corset dress with a low neckline and voluminous skirt. She accessorized with opera gloves and blinged-out sunglasses and a diamond necklace. Richie, 42, went for a sleeker option — a floor-length halter dress with a sexy keyhole slit — but also wore shades like Hilton.

The two took their twinning to another level with matching pageant-level buns and bold glam.

They showed off their looks in front of the Saban Theatre with a sign reading “Paris & Nicole The Encore.”

After The Simple Life ended in 2007 following a five-season run — which saw the dup travel across the U.S. picking up odd jobs and, eventually, entering the corporate world — Hilton and Richie embarked on different paths as businesswomen and moms, but still remained close.

And they will most definitely be bringing back their iconic antics for the reboot.

On Aug. 6 the stars were seen filming at a Sonic Drive-In in Duarte, Calif. which involved Hilton in a Sonic uniform — accessorized with Swarovski sunglasses, of course — and Richie in a hot dog suit.

Back in June, Hilton told E! News that the “reboot is going to be iconic.”

“I’m so excited to be doing with this Nicole on Peacock. Nicole has been my best friend since we’re 2 years old, every memory that I have is with her,” the DJ and heiress told the outlet. “I can’t wait for fans to see.”
