Julianne Hough stars in the upcoming Grease: Live, set to air on Sunday evening on Fox. She plays the part of Sandy, the iconic role made famous by Olivia Newton-John in the original film.

During an interview with Entertainment Weekly on Thursday, the Dancing With the Stars alum talked about the trouble she’s having with one line in the production–not because she can’t memorize it, but because it touches at the core of who Julianne Hough truly is.

“It’s a line that I should be able to deliver because it’s so me,” Hough said.

Julianne Hough delivers the line while the main cast is inside the diner.

Hough–as Sandy–says, “Who wants to watch a bunch of amateurs in a dance contest on live TV?”

The line references the school dance being filmed on national TV, as is shown later in the show. It was added solely for Julianne Hough because of her past with Dancing With the Stars.

“I mess it up every time,” she says.

“The diner scene is the death of me for sure,” she adds.

Early photos released of Julianne Hough in character as Sandy are reminiscent of Olivia Newton-John’s Grease era. Aaron Tveit plays Danny Zuko–the role John Travolta made famous in the film.
