Julianne Hough ‘Nervous’ To Play Sandy In ‘Grease: Live,’ Looks For Advice From Brother Derek Hough

Julianne Hough has chills – and they’re multiplying! The “Dancing With the Stars” judge opened up about how anxious she is to take on the beloved “Grease” character Sandy (a role that was originally portrayed by Olivia Newton-John in 1971) in Fox's upcoming live production of the musical “Grease: Live.”

"Those are some big shoes to fill so it's exciting, but it's also a little nerve-racking," Hough dished to US Weekly. "It's such an iconic role. It's an iconic musical. I want to do it justice. But I'm very, very excited. I would say I'm more excited than nervous."

The blond haired actress, who previously showcased her vocal talent in the 2012 flick “Rock of Ages,” added that despite the nerves, she’s looking forward to embodying the goody-two shoe-turned bad girl character.

"I'm not nervous in a terrified way. I'm nervous in an excited way," she explained. "I can't wait to get started. It's like the first day of school for sure when you have a new path and you kind of don't know what you're getting into yet even though you know the story."

The dancing darling also revealed that she has a support system cheering her on as she embarks on this new and exciting journey in her life – her number one supporter being her older brother Derek. According to the sandy-haired star, her big bro has given her encouraging advice as she tackles the modern-day version of Danny Zuko’s beau.

"We're both each other's mentors in a way. I wouldn't say that one is more of a mentor than the other but we're there to feed off of each other," Hough told US Weekly. "I love getting advice from him and I think vice versa too. I definitely give him a lot of advice, whether he wants it or not."

Although Hough has friends and family backing her up as she heads over to Rydell High, the crooner knows not everyone will be impressed with her interpretation of Sandra Dee.

“It’s the adrenaline and the pressure that you have to deliver,” Hough, who watched both “Sound of Music Live!” and “Pete Pan Live!,” told Yahoo! Style. “I know there’s going to be some haters, but hey, I’m living my dream. I get to be Sandy in Grease! How awesome is that?”

Hough elaborated in a Fox press release how grateful she is to be apart of the 2016 musical.

“'Grease' is one of the movies that made me want to be an entertainer, and I have literally been waiting my whole life to play Sandy," Hough gushed. "My siblings and I watched it and played it out over and over when we were kids. This is my dream role and performing it live on television will be one of the most thrilling opportunities I’ve had in my career so far."

Hough will revive the classic musical alongside Aaron Tveit as Danny Zuko, Vanessa Hudgens as Rizzo, Keke Palmer as Marty Maraschino and Carlos PenaVega as Kenickie when “Grease: Live” debuts on Fox in 2016.
