There was a scare in Hollywood on Monday when a suspicious package addressed to Bill Maher was reported to authorities — and the powerhouse management firm that reps the comic had to evacuate its offices. Sources told Page Six that Brillstein Entertainment — which reps Maher, as well as Brad Pitt, Rob Lowe and Courteney Cox — had been warned by authorities that Maher’s name was on a list of potential targets by alleged mail bomber Cesar Sayoc, as was Brillstein’s Wilshire Blvd. address.
