Jennifer Aniston and fiancé Justin Theroux held hands walking into the “We’re the Millers” premiere party at Bryant Park Grill Thursday. Director Rawson Marshall Thurber commented on the pair: “Justin and Jen are a lovely couple. They’re in love.” Emma Roberts stayed half an hour before heading to The Sea Fire Grill, where she was heard gushing about how great things are with boyfriend Evan Peters, even after an alleged domestic-violence dispute.
