Woody Harrelson got some extra support from his “Hunger Games” co-stars when Liam Hemsworth, Josh Hutcherson and Jennifer Lawrence crashed his opening monologue on “SNL” on Saturday.

After mentioning that the first time he hosted the show was back in 1989, Harrelson grabbed a guitar and performed his own version of “Blank Space” to school Taylor Swift about what really went down 25 years ago. “I got a blank space, baby, cause I used to do cocaine,” he sang.

Then, Liam Hemsworth, Josh Hutcherson, and Jennifer Lawrence showed up to help Harrelson finish the song — even though, as Hutcherson pointed out, none of the three were even born in 1989. Watch the full clip above.
