Jennifer Aniston was spotted with Emily Blunt in their bikinis while sunbathing in Cabo San Lucas on New Year's Eve.

The two were a part of a major low-key gathering of celebrities that included Aniston and her fiancé Justin Theroux, Blunt and her husband John Krasinski, and Jimmy Kimmel with fiancé Molly McNearney.

The group was spotted on a terrace relaxing outside in the sun which eventually led to the Hollywood beauties basking in the warmth in their bikinis, according to E! Online.

Aniston and Theroux spent the Christmas holiday at the resort in Cabo San Lucas and planned on spending New Year's there as well with their fellow Hollywood pals.

The big name group got together for a post-Christmas bash that may have been linked to a secret wedding that was planned and canceled by Aniston and her 41-year-old fiancé, according to a source for OK! Magazine.

The wedding was supposed to be an intimate beach wedding ceremony with a small gathering of friends and family.

"Originally they wanted to fly everyone to Cabo San Lucas, Mexico, for a small barefoot-on-the-beach ceremony, but that plan was scrapped after the details were leaked," claimed the source, as reported by MTV News.

The recent pictures of Aniston and Blunt are not the only photos of the 43-year-old former "Friends" actress.

While relaxing in the sun, Aniston was caught by paparazzi with her toned body and flat abs in a pink bikini top with a sarong while lounging poolside at the hotel cabana. Theroux flaunted his six-pack abs wearing only a pair of swimming trunks.

The couple has also been spotted sharing romantic embraces and kisses during their Mexican vacation.

Theroux popped the question to Aniston in 2012 and they are expected to tie the knot within the new year.
