Jennifer Aniston is off the market.
"Justin Theroux had an amazing birthday on Friday, receiving an extraordinary gift when his girlfriend, Jennifer Aniston, accepted his proposal of marriage," his representative told People.com Sunday.
No other details about the proposal were immediately reported.
Former "Friends" star Aniston was previously married to actor Brad Pitt, who is now with fiancee Angelina Jolie.
Theroux, who co-starred with Aniston in the big-screen comedy "Wanderlust," broke up with Heidi Bivens, his girlfriend of 14 years, in 2011.
