Here's what went down.
Back in October, Kelly appeared on British comedian Alan Carr's show "Chatty Man," where she discussed the possibility of Gaga being pregnant:
I think she is pregnant because she has been covering up this part of her body recently and I have been noticing that a lot.
Following the appearance Kelly, complained about Gaga's fans attacking her on Twitter in an issue of "Fabulous" magazine.

I get called fat all the time. A big fat whore. Lady Gaga’s fans are the worst. They’ve said I should kill myself, that they hope I get raped. I mean it’s crazy but I’ve had this all my life and I just try and ignore it.
