It's been nearly two months since Justin Theroux popped the question to Jennifer Aniston, and the actress has successfully hidden her engagement ring from the public - until now.

After months of Aniston playing coy and hiding the ring from the paparazzi, photographers finally snapped a photo of the enormous diamond this week as Aniston and Theroux were out and about.

The ring is especially large, and The Huffington Post described it this way: "Now that we've seen the actual engagement ring in it's full glory, we have to say we're impressed. Who knew Justin had such luxurious tastes? The rock practically takes over half of her finger."

Theroux apparently enjoys spoiling Aniston with expensive jewelry. He recently stopped by the Beverly Hills location of Tiffany & Co. to pick up a surprise for his fiancé, and by the time he left the store he had dropped a ton of cash on a $15,000 platinum heart pendant accentuated with sapphires.

"Justin thought the necklace was a couple of thousand - and went into shock when the saleswoman told him it was just more than $15,000," a sourced told The National Enquirer. "He took a big gulp, pondered a minute, then said, 'Oh what the hell!' He told the woman to wrap the bauble, saying he'd save it for a special occasion."

The couple has reportedly begun making wedding plans, but the primary thing on Aniston's mind, according to friends, is getting pregnant. The actress wants to have a baby as soon as possible, even if that means it happens before her big wedding ceremony.

"In truth, she'll be overjoyed whenever it happens; if that means she has to walk down the aisle with a baby bump and do her toasts with apple cider, then so be it," a source said.
