Kate Gosselin is in the middle of another nasty battle, and it may be the ugliest one ever!

A war between pro- and anti-Kate camps has been raging on Twitter, but now it’s gone nuclear as the group @Bullyville named what they claim is Kate’s stalker, Breaking Celebrity News is reporting.

And that stalker, they claim, is a senior citizen -- a 62-year-old woman! (Breaking Celebrity News is not naming that person or giving out her Twitter account.)
