During her five-year marriage to Brad Pitt, Jennifer Aniston sported a swirly engagement ring the size of a baby's fist. So, how big is the sparkler currently weighing down her finger, courtesy of newly minted fiancé Justin Theroux?
Life & Style says the actor-writer-director presented Jen with a "huge emerald-cut diamond" with tapered baguettes dotting the sides. The ring is estimated to be a knuckle-crunching eight carats and is, gushes one source, "beautiful."
"She was so happy and said she loves the ring," enthuses an insider. "I think she was overwhelmed and overjoyed by the size and beauty of it!"
Theroux surprised (and presumably temporarily blinded) Aniston with the rock during a quiet dinner at Manhattan eatery Blue Hill on Aug. 10, his 41st birthday, reports People.
The two had jetted to New York on a private plane from North Carolina, where the actress has been shooting "We're the Millers," and as they sat side by side over a quiet meal, Theroux popped the question.
"Jen cried," a source tells Us Weekly. "The proposal was simple. He was surprised she said yes, but he is so happy."
A Theroux confidant adds to People, "He's been dying to do it. His friends knew it was coming."
After Aniston, 43, gave him the "extraordinary gift" of accepting his offer, they called close pals and family.
"Everyone is really excited for them," a spy shares with the mag. "It's amazing to see how happy Justin makes Jen, and everyone was always hoping that he would propose."
The couple of a year and a half work because "they have the same low-key attitude about life," explains an insider. "They just click and complement each other."
But will that low-key attitude lead to an equally understated wedding? Read on for more, including how Pitt may figure into this happy time …
