Through an agreement with Bagdasarian Productions and Twentieth Century Fox Licensing & Merchandising, the singing stars of television and film were recreated as 18-inch tall figures.

Madame Tussauds said they are the smallest likenesses installed in any U.S. branch of the famed museum chain.

Visitors will be able to pose with Alvin, Simon and Theodore, and sing in a Chipmunks-style karaoke session, the company said.

"Alvin and The Chipmunks are true stars and this milestone is evidence of their enduring popularity," Michael Peikoff, senior vice president of 20th Century Fox licensing and merchandising, said in a statement. "The property continues to resonate with generations of fans across all age groups and demographics -- we are honored to have Alvin, Theodore, and Simon enshrined for the entire world to enjoy in this special, groundbreaking initiative."
