In the video, the ladies combine their signature "Bo$$" moves with a little bit of Halloween-ish sass as they work overtime to convince us why hooking up with a rebellious monster-like bad guy might not be such a bad idea. After watching them serve some majorly fierce attitude and spine-chilling vocals, we totally understand why Taylor Swift temporarily appointed herself as the group's honorary sixth member during a recent stop on her star-studded 1989 tour. Harmonizers and Swifties are likely still getting their lives to Tay and 5H's sassed up rendition of "Worth It."
As for "I'm in Love With a Monster," the upbeat single is featured on the upcoming Hotel Transylvania 2 soundtrack, which will be available on Sept. 25. Obviously, Fifth Harmony's contribution gets ALL of the yeses from us. But if the rest of the soundtrack comes anywhere close to the complete and utter hotness that is "I'm in Love With a Monster," then we're on standby to download because we already know it'll totally be worth it.
