"Hey everybody, it's me, Kathy Griffin. I sincerely apologize. I'm just now seeing the reaction to these images," Griffin said in a video posted to her Twitter account. "I'm a comic. I crossed the line. I moved the line, then I crossed it. I went way too far."
"The image is too disturbing. I understand how it offends people. It wasn't funny. I get it. I've made a lot of mistakes in my career. I will continue. I ask for your forgiveness," she continued. "I'm taking down the image, and asked the photographer to take down the image, and I beg for your forgiveness."
"I went too far. I made a mistake, and I was wrong," Griffin captioned the clip.
Earlier in the day, Griffin defended the photo shoot with since-deleted tweets, calling Shields a "great photographer."
"OBVIOUSLY, I do not condone ANY violence by my fans or others to anyone, ever!" she wrote. "I'm merely mocking the Mocker in Chief."
