Jennifer Aniston has finally announced she is engaged to Justin Theroux! The couple announced their engagement at the weekend after Justin popped the question to Jen on Friday at his birthday party. They began dating over a year ago since they worked together on comedy Wanderlust but have known each other for years. This will be the second marriage for Aniston after her divorce to Brad Pit in 2005. No date for their wedding has been announced yet, but we think it will be a quiet affair. We are still yet to see the engagement ring Jen said yes to, but if you look closely at the image below taken after the engagement news you can see a ring on her wedding finger.
