The pair's reunion comes just a few months after the 10-year anniversary of "Mean Girls" back in April. Written by "30 Rock" creator Fey, the 2004 flick starred Lohan as a formerly homeschooled student who falls in with the catty but popular Plastics clique -- played by Rachel McAdams, Lacey Chabert, and Amanda Seyfried. Fey costarred as Ms. Norbury, Cady's math teacher.

Lohan and the "SNL" vet also reunited back in February, when both appeared on Jimmy Fallon's first episode of "The Tonight Show." Returning to the late-night staple in March, the Liz & Dick star told Fallon that she and Fey had talked about a "Mean Girls" reunion.
