Joan Rivers: Kelly Osbourne's 'Feelings Get Hurt Very Easily'

Lady Gaga isn’t backing down after her back-and-forth with Kelly and Sharon Osbourne last week, responding to the open letter Sharon posted. And neither is "Fashion Police" star Joan Rivers or the E! network.

“Kelly talked about Gaga fans in January and now she is responding. She is the slowest reader in the world,” Joan tells The Huffington Post. “I think she is doing all this to get attention as her tour isn’t selling. Everything this woman does is about getting attention. I think she is a genius.”

All the drama started when Kelly said she thought Gaga might be pregnant because of her noticeable weight gain at the 2012 Grammys. After that, Kelly started getting nasty messages from Gaga’s fans. Finally, Kelly told the U.K.’s Fabulous magazine, “Lady Gaga’s fans are the worst.”

Since then, mom Sharon has written an open letter to Gaga.

“The only thing that really upsets me is that Kelly is an open wound. Her feelings get hurt very easily. She’s a sweet person, she never wants to say anything bad about anyone,” reveals Joan. “She takes everything so personally. But, at 'Fashion Police,' we are like a family, and if you mess with one of us you mess with all of us. If Gaga wants to keep this up then fine, it’s more publicity for all of us, but she needs to pick on someone her own size.”

“We value strong points of view on our air and greatly appreciate the clever commentary and opinions of our ‘Fashion Police’ team,” an E! Spokesperson tells The Huffington Post.
