|Jennifer Aniston and Fiance, Justin Theroux|
The former Friends star jetted to the Big Apple - where she grew up and went to school - for the weekend, which she had off from filming We Are The Millers.
And on Friday night - Justin's actual birthday - it was him doing the gift presenting as he whipped out an eight-carat, emerald-cut diamond ring.
A representative for the Blue Hill restaurant told the New York Post's PageSix column: 'We are thrilled about the news of their engagement, but we cannot comment on any guests.'
A source told Life & Style magazine: 'It's a huge emerald-cut diamond. It's a rectangle with tapered diamond baguettes on the sides. It's beautiful.
'Just after Jen got engaged, she called all her friends and told them about it. She was so happy and said she loves the ring. I think she was overwhelmed and overjoyed by the size and beauty of it!'
