Louis CK wears Charlie Hebdo T-shirt on stage

Comedian Louis CK showed his support for Charlie Hebdo by wearing a self-made T-shirt bearing its name.

CK wore a red shirt with the French satire magazine's name written in black ink while performing at New York City's Madison Square Garden, according to Hollywood Reporter.

Twelve people were shot dead by masked gunmen at the magazine's office in Paris on January 7, including several of its key cartoonists.

CK's shirt is the latest in many messages of support to those killed and injured in the attack, while also defending the right for freedom of speech.
