Robin Thicke, Jessie J and DJ Cassidy Collaborate for 'Calling All Hearts' Music Video: PHOTO from Pink, Vintage-Inspired Set Appears Online Before Trio Tour Together in 2014

A series of tweets and a behind-the-scenes photo have confirmed a collaboration is in the works with "Blurred Lines" singer Robin Thicke and "It's My Party" songstress Jessie J. The duo recorded a duet together, "Calling All Hearts."

On Sept. 25, Jessie J tweeted, "That's a wrap! Woooooo! Amazing video! @robinthicke @djcassidy," confirming that "Calling All Hearts" would receive an official visual. Later, Thicke retweeted her and added, "Going to be awesome. Can't wait for everyone to see."

"Calling All Hearts" is reportedly a part of an upcoming project for DJ Cassidy.

Later a photograph from the set of the music video hit the web, as seen above.

The very pink photograph features Thicke in a black and white suit, sans jacket, and Jessie J rocking a baby pink ensemble. DJ Cassidy stand in the middle of the two, rocking mint green behind his turntables.

The set is clearly inspired by '60s Havana-style clubs. Palm trees and a vintage looking sign decorate the set, as sweater-wearing musicians back up Thicke, Jessie J and DJ Cassidy.

"Calling All Hearts" has yet to be heard by fans, and a release date for the music video has yet to be set.

This isn't the first collaboration between Thicke, Jessie J and DJ Cassidy. The three will hit the road together in February 2014 together for a tour in support of Thicke's hit album "Blurred Lines."

The 15-city string of shows will kick off Feb. 21, 2014, in Atlanta.
