The voice cast of "Toy Story 4" is already chock-full of Hollywood mega stars —  but they'll have to make room for four comedy icons.

USA Today reveals that Betty White, Mel Brooks, Carl Reiner and Carol Burnett are adding their voices to the toy box. They join returning stars Tom Hanks and Tim Allen.

Their characters all have punny names that reflect the legends (below, from left to right): the kid seat Chairol Burnett; purple Melephant Brooks; teething tiger toy Bitey White; and pink Carl Reineroceros;

“It was wonderful the way they incorporated our names into the characters,” White told USA Today. “And I’m a sucker for animals, so the tiger was just perfect!”

In the movie, Woody and the gang settle into their new owner Bonnie's home and meet the now-discarded baby toys, who reminisce about their time in the spotlight.

The whole toy crew then welcomes a new member to the fold: Forky (Tony Hale). But when Forky runs away, Woody follows and finds himself lost ... until he runs into old gal pal Bo Peep (Annie Potts). Bo opens his eyes to a whole new world — and sets Woody to reconsidering his future.

The movie will feature several other new toy characters, including a menacing pull-string doll (Christina Hendricks); Duke Caboom, a motorcycle-riding stuntman action figure (Keanu Reeves); a two sassy carnival prizes (Keegan-Michael Key, Jordan Peele).

"Toy Story 4" opens in theaters June 21.
