Courteney Cox, Amy Poehler and Ice-T are among the stars who have joined forces with actress Mariska Hargitay to take a stand against domestic violence and sexual assault in a new public service announcement (Psa).

Fellow actors Debra Messing and Tate Donovan also appear in the new No More advertising campaign in an effort to raise awareness about the crimes and encourage bystanders to help victims.

The Psas, directed by Hargitay for the Joyful Heart Foundation, feature a new circular blue symbol for the No More drive, and the Law & Order: Special Victims Unit star hopes the logo will become synonymous with the fight against domestic violence and sexual assault.

She says, "This is an epidemic that is afflicting our society and I believe that it is an epidemic we can change. For the first time in history, the domestic violence and the sexual assault movements, the two communities, are coming together with this symbol. It's to this movement what the pink ribbon was to breast cancer, what the red ribbon did for Hiv/Aids; it got people together, under one umbrella, talking about it."

Hargitay adds, "The shame and stigma belongs with the perpetrator. Let's not stand by; let's not accept it anymore. No more."
