Jennifer Aniston and Justin Theroux are ringing in the New Year with sand, surf, and celebrity friends.

Aniston, 43, and her screenwriter fiancé of four months celebrated their unforgettable year by capping it off in sunny style, while vacationing in Mexico with late night talk show host Jimmy Kimmel and his fiancée Molly McNearney (who coincidentally got engaged just days after Aniston and Theroux on Aug. 15), and happily married pair John Krasinski and Emily Blunt.

The trio of loved-up couples lounged in Los Cabos Dec. 27 on a private terrace as Blunt cuddled with her funnyman and Theroux and his leading lady took in the good company over conversation and appetizers. At one point, Kimmel even snuck in a sweet embrace with his wife-to-be, who he began dating in October 2009 — a few months after he split from fellow comedian Sarah Silverman — during a late summer getaway to South Africa’s Kruger National Forest.

Earlier in the day, the future Mrs. Theroux — who said yes to her beau of more than one year on Aug. 12 — continued to show off her enviable figure in a black bikini top and red sarong, showing off her toned tummy and tanned arms.

The brunette beauty also had some one-on-one moments with her tattooed man as they caught some rays and enjoyed a tortilla chip snack. Aniston definitely let her hair down on this relaxing vacation as she read a book, while Theroux, 41, got a good laugh reading a script.

The Friends star has a tradition of leaving the winter blues behind for some fun in the sun every year on the beaches of Cabo and has spent previous years south of the border with pals Chelsea HandlerCourteney Cox and even former beaus John Mayer and Gerard Butler.
