A rift between Courteney Cox and Jennifer Aniston has been healed by an unlikely mediator - the Along Came Polly star's ex-husband Brad Pitt. The Friends co-stars reportedly fell out over Cox's failure to visit Aniston on the Oregon set of her upcoming movie Management, according to British newspaper The Sun. But the Fight Club star heard of the argument and contacted Cox's husband David Arquette to devise a plan to reconcile the long-time pals. A source says, "He (Pitt) can't bear to think of Jen lonely."
