As referenced in the actress’ hashtag, this marks a National Lampoon’s Christmas Vacation reunion for Galecki and Lewis, who played siblings Rusty and Audrey Griswold respectively in the 1989 Chevy Chase film. So in more ways than one it’s a family reunion, and fans definitely won’t want to miss it.
