Jennifer Aniston engaged to actor/writer Justin Theroux

NEW YORK -- After years of breathless anticipation -- at least on the part of the tabloids -- Jennifer Aniston is finally ready to wed again.

Her representative, Stephen Huvane, confirmed Sunday night that the actress is engaged to her boyfriend of more than a year, Justin Theroux.

"Justin Theroux had an amazing birthday on Friday, receiving an extraordinary gift when his girlfriend, Jennifer Aniston, accepted his proposal of marriage," said Theroux's rep in a statement to People, which first reported the engagement.

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." Though that film disappeared quickly from movie theaters after its release earlier this year, the relationship clearly proved to have more staying power. The two moved in together and tabloids soon began predicting everything from marriage to babies for the new couple.

Aniston had been a part of such speculation for years, ever since the demise of her marriage to Brad Pitt after a five-year union in 2005. While Pitt moved on to a long-term relationship with Angelina Jolie, Aniston had high-profile relationships with the likes of John Mayer and Vince Vaughn that didn't last, leading to the common narrative: When will Jen find someone or have a child?

It's a theme that irked the former "Friends" actress.

"It's very narrow-minded, I think. It doesn't measure the level or my happiness or success in my life and my achievements or any of that," she told "CBS This Morning" earlier this year. In the same interview, she said she was happier than she'd ever been.

This will be Theroux's first marriage. It's not clear if a wedding date for the couple had been set.

Aniston's engagement comes four months after Pitt and Jolie announced their engagement.
