The 27-year-old actress has been engaged to hockey player Brooks Laich since August 2015, but admits she hasn't planned anything when it comes to her nuptials.

She said: "I'm honestly the worst bride ever - I haven't done anything!"

Julianne made the admission as she appeared on 'Good Morning America' on Monday (18.01.16).

The multitalented star looked incredible in a one-shouldered orange top and matching wide legged cropped trousers.

Julianne's latest role will see her star alongside Zac Efron in 'Dirty Grandpa'. But she insists she shares absolutely nothing in common with her character in the film.

She continued: "I'm the fiancé to Zac Efron and I'm that kind of uptight fiancé. I hope that I'm not anything like that character Meredith in Dirty Grandpa - she's actually quite awful."

She will also be showcasing her vocal and acting talents in the live action version as she stars as Sandy in 'Grease: Live!'

The project also stars Vanessa Hudgens and Carly Rae Jepsen, and Julianne says she jumped at the chance to work on such a unique project.

She said: "It's not every day you start a project and you're in it and you're like 'wow, this is one of the most special iconic things I've ever been a part of'. I mean Grease in general has been such a staple in our culture and our lives."
