The newlyweds shone on the red carpet at a screening of HBO's The Leftovers in Austin, Texas on Sunday evening (4 October).
Jen beamed for the cameras as she kept an arm around her man as they walked the red carpet at the Paramount Theatre.
The couple - who both wore black - married in a secret ceremony held at their Bel-Air, California mansion in August and only announced to the public after it happened.
Guests included Jen's former Friends co-stars Courteney Cox and Lisa Kudrow, along with Hollywood stars Ellen DeGeneres, Jimmy Kimmel, Emily Blunt and John Krasinki.
They'd been engaged since August 2012.
In a twist to convention, the newlyweds decided to take their friends on honeymoon with them. Justin recently told Extra: "It was a fantastic honeymoon. We had thought about it; we could just do a normal honeymoon, or we could keep the party going, relax, and have fun. It was really special, it was really beautiful."
