Jennifer Aniston is engaged to marry her partner of more than a year, screenwriter and actor Justin Theroux.

Her representative, Stephen Huvane, confirmed the news on Sunday night.

Theroux, 41, and Aniston, 43, have known each other for years, but started dating more than a year ago after working on the comedy Wanderlust.

Theroux – whose screenwriting credits include Tropic Thunder, Iron Man 2 and Rock of Ages – popped the question on Friday, which was also his birthday.

“Justin Theroux had an amazing birthday on Friday, receiving an extraordinary gift when his girlfriend, Jennifer Aniston, accepted his proposal of marriage,” Theroux’s representative said in a statement to People.

This will be 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.

It’s not clear if a wedding date for the couple had been set
