It's not like we didn't think that A-lister Jennifer Aniston would like a bit of bling.

But our mouths fell open at the size of her engagement ring from Justin Theroux when these first pictures landed on our desks today.

The Hollywood actress *FINALLY* debuted her rock this weekend as she stepped out with her fiance in Santa Fe, New Mexico.

The couple - who got engaged in August - looked as loved-up as ever as they left their accommodation for a romantic stroll.

The betrothed pair looked relaxed in jeans and casual jackets as they took time out of their hectic schedules to be together.

Jen has been filming latest movie, comedy 'We're The Millers' in nearby Albuquerque.

Justin popped the question back in August, to coincide with his 41st birthday (and to steal the limelight away from her ex Brad Pitt and Angelina Jolie who were reportedly getting hitched that weekend) but the pair have remained low-key since about their wedding.

The 'Friends' star was seen shortly afterwards wearing a simply gold band on her wedding finger.

And although they've been tight-lipped about when they will tie the knot, OK! Magazine report that they may well chose holiday destination Mexico as the location.

A source told them: "Jen has fallen in love with New Mexico, it has a very relaxed vibe that fits both her and Justin perfectly, so it would be a great place for them to have the wedding."

A source told US magazine that Jen and Justin have been eyeing up Julia Roberts' New Mexico ranch as a potential venue AND they've had yet another celeb acting as their wedding coordinator.

No doubt it'll be SOME wedding.
