Goodbye Isla Fisher, hello Kristen Bell.  Disney has a new romantic comedy leading lady.

According to The Hollywood Reporter, Bell has joined the cast of "You Again," a new rom com from "Race to Witch Mountain" director Andy Fickman.

The story follows a young woman (Bell) who discovers her brother is marrying the one person who made high school a living hell for her.  She immediately sets out to show the true colors of her potential sister-in-law.

This is the second picture in a row with Disney for the former "Veronica Mars" star.  Bell also appears in the studio's "When in Rome" which opens this August.  She also recently wrapped Universal's comedy "Couples Retreat" alongside Vince Vaughn, Jon Favreau and Jason Bateman.

Production on "You Again" should begin sometime this summer.
