It looks like Rose McGowan is seeking new representation.

The former Charmed actress says she was fired by her agent after she publicly slammed a casting call as sexist. She later said that the audition was for a project starring an actor whose name “rhymes with Madam Panhandler,” spurring online speculation that she was referring to Adam Sandler.

On Wednesday, McGowan took to Twitter, writing that she’d been fired by her “wussy” acting agent for pointing out “the bull— in Hollywood.”

The message comes a week after the actress-director, 41, criticized the wardrobe description for a movie audition. A screengrab of the alleged casting call, which she Tweeted, advised actresses auditioning for the role to show off “cleavage” and wear “form fitting” clothing.

Sandler has not directly responded to McGowan’s comments, but a source close to his production company, Happy Madison, tells PEOPLE, “They [Sandler and his team] were not aware the casting director sent this note out. They felt it was completely inappropriate and have made sure that it has not been sent out again.”

PEOPLE has reached out to McGowan’s rep and her agency for comment.
