Remember how she actually cried while filming Mockingjay: Part 1 when she had to sing "The Hanging Tree" in front of the cast and crew?
Well, that same song that J. Law was pertrified to sing has apparently become a runaway hit and even cracked the Top 40 list in England.
The BBC reports the track, which was cowritten by The Lumineers, is currently at #29 on the UK charts, according to mid-week sales.
The 24-year-old Oscar winner revealed to David Letterman that she originally requested Lorde, who curated the whole soundtrack, sing the tune for her.
"I was like, 'Will you guys please get Lorde to really sing it?' and I'll lipsync it and they said no," Jen explained.
Leave it to Jen to score a hit when she wasn't even trying!
