Fifth Harmony have already released one of the hottest songs of the summer with their hit "Worth It," and the girls are getting ready to release a fun, spook-filled music video for their new single "I'm in Love With a Monster."

ET's Katie Krause went behind the scenes exclusively to talk to the girls of Fifth Harmony about the song and the concept behind the monstrous music video -- while the girls (mostly) stayed in character.

"Basically we all have different characters," Camila Cabello said, explaining the creepy-sexy costumes and Halloween themed decor. The song is featured in the upcoming animated film Hotel Transylvania 2 (starring Adam Sandler, Andy Samberg and Selena Gomez) and the music video matches the film's fun, gothic style.

"It's so fun though because we've never done a music video like this where we get to play characters and be funny and show personality," Camila added. "So this is like probably my favorite music video that we've done."

Set in a dark fantasy version of a 1940s hotel, the music video for "I'm In Love With a Monster" is full of classic scary movie staples including moody architecture, creepy decor and an impractical number of candles.

But outside of their exciting music video, the song itself raises an interesting question: out of all the members of Fifth Harmony, who is the most likely to fall in love with a "monster," or maybe just the wrong kind of guy.

As it turns out, the answer is apparently every one of them.

"I would say definitely all of us," Normani Kordei admitted. "I mean there's definitely different types of monsters. I would say I'd fall in love more so with a werewolf."

"For me sort of more of a vampire," Lauren Jauregui added.

"[For me] it would be Frankenstein," Dinah Jane Hansen chimed in. "I would love to be his wife. Put a ring on it, you know?"

But outside of the realm of mythic monsters and supernatural beasts, it looks like main type of "monster" the girls fall for is your typical "bad boy."

"I do love me some bad boys," Camila admitted.
