They say couples take after each other! Jennifer Aniston and her fiance Justin Theroux swapped their dolled-up Leftovers premiere outfits for more casual looks during a Tuesday, June 24 outing in NYC.

The engaged couple stepped out of their Manhattan hotel, both wearing head-to-toe black and matching aviators. Aniston, 45, showed off her toned arms in a tight black tank and ankle-length pants. The Cake star wore flat black sandals and draped a blue denim jacket over her purse as she trailed behind her beau, 42, who looked handsome in stonewash jeans and a polo T-shirt.

Their latest excursion in the concrete jungle took place the morning after the two attended the premiere of Theroux's new show, The Leftovers, at the NYU Skirball Center on Monday, June 23. An observer on the red carpet said the couple "looked happy and totally in love," adding they "were both absolutely beaming."

As if he couldn't be happier to celebrate his new show, Theroux "lit up" when he was asked about Aniston joining him on the red carpet. "It feels great!" he said of his fiancee's support, which was also her first red carpet appearance in months.

Aniston would have also loved Theroux's response to one reporter's question, in which he was asked who he would bring along if he were taken in the rapture. Without hesitation, Theroux responded of the A-list actress: "That's who I'd want to bring with me!"
