Jennifer Lawrence "freaked out" when Lorde visited the set of The Hunger Games: Mockingjay - Part 1.
The 24-year-old actress got star-struck when the Royals singer came to meet the cast and watch a shoot of the new fantasy film because she is such a big fan.
Speaking about the pop star's trip to the set, Lawrence said: "It was so cool, oh my god! The whole set freaked out, everyone stopped and it was like, 'Be normal! Be normal! Be cool!'"
The 18-year-old performer has curated the soundtrack to the franchise's third film, as well as writing and recording the track Yellow Flicker Beat especially for the film, and Lawrence loves the track.
"I mean, you read the book and internalise the character and go on set and have conversations with the director and your co-stars but it was so bizarre to hear a musical version of what, emotionally, I feel."
The Oscar winner also believes her Hunger Games alter ego Katniss Everdeen would be a huge fan of the Team songstress.

She said: "Honestly, the first time I ever heard that Lorde song, Yellow Flicker Beat, it just gave me goosebumps.
Lawrence said: "I think she really captured that character so magically that it was a really amazing thing to listen to, so I think Katniss would be a huge Lorde fan. And obviously Taylor Swift."
Speaking about the decision to enlist the young singer to work on the film's soundtrack, producer Nina Jacobson added: "There was truly nobody who made more sense than Lorde. It was kind of a no-brainer in that regard.
"It felt like such a natural fit and she came and visited us on set. I think we were all a bit starstruck!"
