The Jurassic World: Fallen Kingdom actor, 38, made no mention of his split during Monday’s monologue, but did express his nerves about being Kimmel’s replacement.
“You know I was actually – I was kind of nervous to do this tonight, because… you know – I’ve never done anything like this,” Pratt told viewers.
In addition, the father of one had some fun with the night’s musical guest, country star Chris Stapleton as they performed a rendition of “Time of My Life,” the theme song from 1987’s Dirty Dancing.
The pair belted out the lyrics of the popular Bill Medley and Jennifer Warnes duet before attempting to recreate the scene where Baby runs to Johnny and executes the lift move.
Pratt took on the role of Patrick Swayze while Stapleton, who is expecting twins with wife Morgane, stepped into Jennifer Grey’s dancing shoes.
After two failed attempts, with some green screen magic, both Chris’s executed one of film’s most famous dancing sequences.
