It's a war of words between Sharon Osbourne and Lady Gaga.
The feud started when Kelly appeared on a British talk show and made a comment about Lady Gaga wearing a burka.
Kelly said, “I think she's pregnant. she's been covering up this part of her body [points to stomach] a lot recently.”
Gaga hit back in an "Open letter to Kelly" on her blog.
"You have chosen a less compassionate path. Your work on E! With the fashion police is rooted in criticism, judgment, and rating people's beauty against one another. To see you blossoming into a beautiful slender woman who makes fun of others for a living is astounding,” Gaga wrote.
Sharon jumped to her daughter's defense, writing this message to gaga on Facebook, “You have shown me that you are nothing more than a publicly seeking hypocrite and an attention seeker."
