On Wednesday, the couple reportedly said "I do" before family and friends at their Bel-Air mansion. Reps have not responded to requests for comment.
Aniston, 46, and Theroux, 43, first met in 2008 but didn't begin dating until 2011. A little more than a year later, Theroux proposed, though neither felt the need to marry right away.
“We just want to do it when it’s perfect, and we’re not rushed, and no one is rushing from a job or rushing to a job,” the actress said in 2013. “And, you know, we already feel married.”
This is the first marriage for Theroux, and the second for Aniston, who was married to Brad Pitt from 2000 to 2005.
