Celebrity Feuds: The Biggest Ever!
Donald Trump vs. Rosie O’Donnell

The pair have kept a years-long feud going on Twitter, often tweeting insults at one another and attacking their respective brands.

I'm starting to miss you!" he tweeted, to which she asked jokingly if he was "trying to kill" her.
