Pop beauty Katy Perry will release 'Unconditionally' as her next single and debuted the official preview for the accompanying music video earlier this evening (November 14). 

Writing on her Twitter page tonight, the songstress confirmed details of the video's impending premiere, which will take place on November 19, and shared a link to the teaser clip: 

"Who's ready for a sneak peak of the #UNCONDITIONALLY video?! #UNCONDITIONALLY premiering on @MTV on November 19th @ 7:53pm ET (tv & online)."

Visually, it looks set to be an exciting offering with dramatic, rich-coloured costumes and a light snow setting as Perry belts out the chorus in a stunning gown. She has also treated her fans to a behind-the-scenes look at the 'Roar' music video, which comes in the form of a 20-minute video and can be viewed below. 

Referring to 'Unconditionally' recently, Perry explained that it was inspired by her boyfriend John Mayer: "'Unconditionally' was influenced by my boyfriend and also really influenced by Africa. I went to Madagascar and did a UNICEF trip that changed my life and gave me this song. It’s just a simple message about loving someone and accepting them and kind of driving at you don’t have to be so self-conscious, you don’t have to fear, because essentially, everybody has their stuff."
