We have a "dirty" girl versus daddy's little girl in a feud between two pop singers. Reportedly, this feud was started by Kelly Osbourne as she bashed Christina in a few interviews saying things such as "Christina is one of the most disgusting human beings in the world... She looks like a drag queen." Ouch!!! As expected, Christina was, should we say, no too happy with the comments. They reportedly got into a little scrap at a club where Christina got Kelly in a headlock and said to her "If you've got something to say, say it now! If you ever want to tell me something, tell me in person!" Christina let go of Kelly and stormed away.
