The National Entertainment Collectibles Association and Twentieth Century Fox Consumer Products have revealed the next set of “The Simpsons” guest stars to be featured in the ongoing consumer products program.

Simpsonized-versions of The Who, Britney Spears, Mark Hamill, Lucy Lawless and Tony Hawk will make their debut on a range of merchandise.

The 25 of the Greatest Celebrity Guest Stars program launched earlier this year in honor of the TV show’s 25th anniversary with Hugh Hefner, James Brown, Yao Ming, Tom Hanks and Kid Rock, which are available now at U.S. retailers including Toys ‘R’ Us and Spencer’s.

The limited edition boutique collections feature an array of products including figures, collectibles, apparel and novelty items, marking the first time that merchandise has been designed around “The Simpsons” celebrity guest stars.

New product rollouts will continue throughout the year, every two to three months, featuring different groupings of guest stars.
