Jennifer Aniston is engaged to screenwriter and actor Justin Theroux.
A rep of Theroux told People magazine: "Justin Theroux had an amazing birthday on Friday, receiving an extraordinary gift when his girlfriend, Jennifer Aniston, accepted his proposal of marriage."
Aniston's rep, Stephen Huvane, confirmed the engagement to The Associated Press.
Forty-one-year-old Theroux - whose screenwriting credits include Tropic Thunder, Iron Man 2 and Rock of Ages - popped the question on Friday, which was also his birthday.
Aniston and Theroux have been dating for about 15 months after meeting on the set of the comedy Wanderlust.
This will be 43-year-old Aniston's second marriage and Theroux’s first. Her union with Brad Pitt from 2000 to 2005 - and their subsequent divorce - became rich material for the tabloids.
After her marriage ended, she was in high-profile relationships with Vince Vaughn and John Mayer.
