Fox is pulling out all of the stops for the Season 3 X Factor finale starting with new judge Paulina Rubio’s debut on the show. During the two-hour December 18 episode, Pau Pau showed us what made her a household name in Mexico and a rising talent here in the U.S.

Performing her dance number “Boys Will Be Boys,” the 42-year-old idol strutted her stuff in a custom designed outfit created by Marina Toybina. The two-time Emmy Award-winning costume designer is the X Factor head of wardrobe and was also responsible for the killer getup contestant Ellona Santiago rocked for her Lady Gaga number.

When designing for an already established talent like Paulina, Marina says she wanted something “Victorian glam rock with a twist of militant avant-garde detailing.” We’d say she hit the nail right on the head with an all-black corseted leather bodysuit complete with feathered shoulders, four-finger half gloves, and oversized cape.

Her blonde locks flying free, Paulina took total control of the X Factor stage and the small army of shirtless men at her command (she even scrawled “Pau” across the bare chests of three hot dudes in what looked to be lipstick). “She did a phenomenal job,” gushes Marina of the performance. “[She] looked incredible and owned the night!”

We second that!
