Two of SM Entertainment's best vocalists, Super Junior's Kyuhyun and f(x)'s Luna, will lend their voices for the upcoming animated film 'The Croods' OST.

Kyuhyun and Luna harmonized their beautiful voices for the song "Shine Your Way", which features a soft and playful melody that children and adults alike can sing along to.

The two singers shared, "This is our first time doing a duet together. We think our voices sound good together, so we're satisfied with the end result. We ask for your love and support for the film and the OST," and "The footage is very beautiful. We're looking forward to the movie because of the interesting story in which a unique family and fascinating animals appear."

'The Croods' will premiere in Korea on May 16th!
