We hope Alice, Buck and "T" are ready to make a new friend.

The three personalities displayed by Toni Collette's character on The United States of Tara are about to greet a fourth.

Series creator Diablo Cody told E! Online that "there may be other alters," though it's since been confirmed that another side to Tara is definitely on the way.

Network sources say to look for "big reveal at the end of this next episode." Reportedly, it will be impossible to miss.
