The 23-year-old starlet was on the set of the highly-anticipated comedy in Atlanta to play the younger model of Kathleen Turner's character, according to THR.

Lawrence has even voiced her love for the original 1994 flick to late-night host Jimmy Fallon back in January.

"I know every word to Dumb and Dumber, Step Brothers and Anchorman," she said.

Fallon quizzed the blond beauty on lines from the film and she passed with flying colors.

Lawrence's surprise role was a convenient job to do as she is currently filming the “Hunger Games” trilogy in Georgia, which happens to be the same state where "Dumb and Dumber To" is presently in production.

Actors Jim Carrey and Jeff Daniels shared photos from the set this week dressed in full costumes as their iconic characters, Lloyd Christmas and Harry Dunne.

The plot to the second installment follows the funnymen on a road trip in search for Harry's long-lost daughter.

"Dumb and Dumber To" is set to hit theaters in 2014.
