Kate Hudson has an amazing set of pipes, which she proved by belting out a tune while promoting Kung Fu Panda 3.

Because the Kung Fu Panda movies are an animated film franchise, the actors' voices are the most important part. Hudson explained to ET that she likes to warm up her voice for optimum performance, which she does through operatic singing.

"I don't know what I'm saying," the Golden Globe winner admitted after making a melody in gibberish. "I've never been to the opera."

She may have never been to the opera, but Hudson is a huge football fan, so you can guess where she'll be a week from Sunday.

"I'm going to be at the Super Bowl," she said.

The third installment of the Kung Fu Panda franchise follows Po (Jack Black) as he reunites with his long-lost panda father and travels to a secret panda paradise. The newfound utopia is threatened when the supernatural villain Kai (J.K. Simmons) begins a path of destruction across China, forcing Po to have to train the village of peaceful brethren to become the ultimate band of Kung Fu Pandas.

Hudson plays Po's love interest, Mei Mei, in the movie.

"She really is a tough cookie," Hudson told ET. "She's so fabulous and then she just turns into this warrior."

Dustin Hoffman, Jackie Chan and Angelina Jolie also star in Kung Fu Panda 3, opening Jan. 29.
