We may be a few weeks out from the official start of the holiday season, but Jennifer Lawrence has already given us our present early.

During her appearance on 'The Late Show With David Letterman' last night (Nov. 12), she treated the veteran host, the audience, and the world to an LOL-worthy rendition of the Burl Ives Christmas classic 'Have a Holly Jolly Christmas.'

Describing her voice with a "tone-deaf, Amy Winehouse" growl, the 'Hunger Games' actress promptly burst into song, bellowing out the festive tune with her trademark sense of humor and one hilariously low register.

Lawrence, who sings in 'Mockingjay' (but wished she had Lorde to dub over her voice) also duetted Christmas song with David Letterman, each note funnier and more ridiculous than the last.

Watch them belt out the tune in the video above!
