The cast of "The Hunger Games" paid a surprise visit on the set of "Saturday Night Live."

Woody Harrelson was doing his monologue and performing a song off of Swift's "1989" album when his two cast members, Liam Hemsworth and Josh Hutcherson suddenly appeared on stage.

After a few exchanges and teasing, Jennifer Lawrence herself surprised Harrelson and all four of them performed a parody of Swift's single, "Blank Space," according to Youth Health Mag.
