Fallon and Lohan participated in a "Water War," a twist on the card game War where the winner of each hand gets to throw a glass of water in the loser's face. Expecting to get drenched, the two took "before" and "after" photos of themselves that Lohan later posted on Twitter.
Lohan's interview was not all fun and games, however. Before the two took to the card table, the actress talked quite seriously about her upcoming docu-series, as well as the misbehavior that landed her behind bars and sent her to rehab.
Lohan gave Oprah Winfrey some credit for her lifestyle change. Lohan's upcoming docu-series Lindsay will air on Winfrey's OWN channel, and she said, "I have a really strong bond with [Oprah] where I can call her for advice and she has become someone I can learn from in life."
The series will document the actress' life since her numerous public dramas. Lohan said, "I became really spiritual over this past year and I have been trying to find peace and serenity of my life. [The show] take[s] the chaos of me moving after eight years of living in LA back to the city of New York."
As for her bad behavior? Lohan said, "That is the past."
Lindsay will debut on OWN this Sunday, March 9.
