By

Pop sensation Carly Rae Jepsen gave ET a behind-the-scenes look at her new music video This Kiss. Click the video for your first look!

VIDEO: Why is Carly Rae Jepsen a Stand-Out Singer?

The concept for the video was "basically just this awesome party." In the clip, the singer has her eyes set on one lucky guy, whom she chases through the different rooms of the party -- each decorated with a different theme.

This Kiss is featured in the upcoming Paramount Pictures/Nickelodeon comedy film Fun Size. Although Carly doesn't appear in the movie, it still boasts a dynamite lineup: Victoria Justice Jane Levy, Chelsea Handler and Johnny Knoxville.

Like the music video, the movie also revolves around a party -- the biggest Halloween bash of the year! Unfortunately, one girl might not be able to make the party because she has to track down her brother who's gone missing.

Fun Size opens October 26.
