Hmm... who didn't see this coming: Rosie O'Donnell has filed a countersuit against Gruner+Jahr, the publisher behind her crumbling magazine Rosie. O'Donnell — who didn't disclose the dollar amount she's seeking — claims G+J breached its contract and forced her to desert her eponymous monthly. On Tuesday, G+J slapped the former talk show host with a $100 million suit.
