Kerry Washington is going to be a regular on 'The Simpsons'

Actress Kerry Washington is set to voice the part of Rayshelle Peyton, Bart Simpson's fourth-grade teacher on the long-running animated sitcom 'The Simpsons'.

Washingtons' alter ego is a replacement for Mrs. Krabappel, who was voiced by the late Marcia Wallace until her death in 2013, reports femalefirst.co.uk.

The 'Scandal' star told Entertainment Weekly: "She's a great teacher. But like all the best teachers, she knows that her students have just as much to teach her as she has to teach them.

"And teaching Bart is a job filled with growth opportunities."

The show's Emmy-winning co-executive producer Carolyn Omine created the part.

She said: "She's really good at figuring out what the kids need, but she can't really figure out what his problem is until he finally comes clean."

Omine had been keen to get Washington on the show after being impressed by her comedic genius when she hosted 'Saturday Night Live' in 2013.
