We got a tease when Katniss sang a few bars of Rue’s lullaby in The Hunger Games, and now we thought we could hear the actress sing an actual song!

In a music video promoting Jennifer’s new horror movie, House at the End of the Street, the 22-year-old seems to be putting her own spin on Benji Hughes’s “All You’ve Got to Do Is Fall in Love.”

As it turns out, the voice is not Jennifer's. Showblitz reports that, while Jen's version of the song wasn't bad, the filmmakers opted to go with the vocals of musician Sarah Rayne. 

In the movie, Jennifer’s character, Elissa, moves with her mother into a house next to one where a grisly crime took place. Ten bucks says that house is haunted.

Check out the song below, but be forewarned, the otherwise-sweet song becomes super-creepy when the video takes a scary turn. It is hyping a horror movie, after all.
