(CNN) Ellen Pompeo is defending her comments about a "toxic" environment on the set of Grey's Anatomy, saying no one person was to blame.

In a series of tweets Saturday, the actress who plays the main character on the hit ABC series, said her words about the show's past unhealthy work environment were meant to inspire and not target anyone in particular.

"Hey! Anyone having feelings over Variety piece. It's not worth getting yourself upset over," Pompeo tweeted. "(N)ot singling anyone out ... as a show we all had a part to play in the environment me included ... as many workplaces do."

Her words came days after she told "Empire" actress Taraji P. Henson in an interview for Variety's Actors on Actors feature that during the first 10 years, the show "had serious culture issues, very bad behavior, really toxic" work environment.

She told people criticizing her not to make assumptions over what she meant.
