Lindsay Lohan visited Jimmy Fallon on The Tonight Show last night to promote her "docuseries" (Girl, sorry, but it's a reality show!) airing on OWN this weekend. They chatted about having a direct line to Oprah (LiLo occasionally butt-dials her) and the possibility of a ten-year Mean Girls reunion (Tina Fey was hanging out backstage). Then Lohan became the first lady in Fallon history to ever participate in Water Wars (basically, where you throw water at each other) while wearing all white. That LiLo, she's up to her old tricks again.
