Julianne Hough is ready to sing and dance as in Fox's upcoming Grease: Live, and the stunning star opened up about what went through her mind when she first saw herself in the bold "Bad Sandy" outfit.

"It was so good," Hough said, sharing that her Sandy Olsson costume "immediately" made her feel as sultry as her iconic character.

Like Sandy and Danny Zuko's instant love connection in Grease, Hough said she knew her husband-to-be was the one for her "the day I met him!"

She also revealed that the most nerve-racking part of putting on a large-scale, live, televised musical is the "behind the scenes choreography."

"We're literally on three different sound stages," Hough explained. "Inside, outside [and] sets in between."

"I'm nervous about one thing in particular: Going from the big dance with Vince Fontaine and the hand jive and everything, and then having two minutes to jump on a golf cart, book it over to Sandy's house, go to the door and then sing 'Hopelessly Devoted,'" Hough shared.

Hopefully it all works out for the multi-talented star when Grease: Live airs Sunday, Jan. 31 at 7 p.m. ET/PT, 6 p.m. CT on Fox.
