The media blitz surrounding Jennifer Aniston's upcoming wedding to Justin Theroux has already reached a fever pitch, but friends say the actress is likely to keep things simple on her big day.

Aniston's nuptials will be relaxed and much smaller in scale than the extravagant affair her ex-husband Brad Pitt is planning with Angelina Jolie, insiders say. No firm plans have yet been made, but the former "Friends" star may opt for an intimate beach ceremony in Cabo, Mexico.

"I would imagine [the wedding will be] tropical and small," her friend Kristin Hahn told Look Magazine.

Cabo is one of Aniston's favorite vacation hotspots, but the location also has a sentimental pull for the couple - it's the place Aniston and Theroux spent their first trip together.

Pals also expect Aniston to keep things simple in her bridal fashion. Sources say she'll likely choose a fitted gown that highlights her physique. One of the designers rumored to be under consideration is Theia Bridal, an elegant label whose mainline collection has been worn by the likes of Taylor Swift and Emmy Rossum.

The 43-year-old actress reportedly wants an understated wedding band as well. Friends say the eight-carat emerald-cut diamond engagement ring is enough dazzle, and Aniston doesn't want another huge rock.

"Friends say Jen's likely to go for something simple by one of her jewelry designer pals like Jennifer Meyer or Anna Sheffield," Look reported.

Fans are still waiting to catch a glimpse of Aniston's engagement ring 12 days after Theroux popped the question. The actress has been coy with her diamond, hiding it under a towel or inside her fist anytime she's been spotted by photographers.
