"All they need is each other. That’s the missing piece they weren’t acknowledging the whole time,” Lohan tells EW.

Ahead of the sequel, Billboard spoke with the women of Pink Slip — Lindsay Lohan, Christina Vidal & Haley Hudson — as well as key producers behind the reunion.

Lindsay Lohan said she performs a more complicated guitar solo when Pink Slip reunites in "Freakier Friday." The actress teased the sequel on "Tonight."
