Jennifer Aniston and Justin Theroux Smooch Under the Mexico Sun

at 10:30 am | By

Jennifer Aniston is back south of the border.

After promoting her latest film We’re The Millers, the actress is enjoying some hard-earned rest and relaxation with fiancé Justin Theroux in her go-to getaway spot: Cabo San Lucas, Mexico.

Aniston, 44, slipped into her favorite crimson-colored bikini — a repeat from her last Cabo trip around Christmastime — to soak up sun poolside with Theroux, 42, sipping SmartWater (like the good spokeswoman she is). While cooling off in the water, she even stole a sweet kiss from her future husband.

Word is the couple are staying at an oceanfront home near San Jose Del Cabo, and are joined by pal Jason Bateman (who costarred with Aniston in Horrible Bosses) and his wife, Amanda Anka, for the beach trip.

Aniston has been vacationing in Mexico for years — even going with past beaus John Mayer and Gerard Butler — and brought Theroux down to the Baja region for a Christmas retreat last year. This trip comes on the heels of Aniston throwing a star-filled 42nd birthday party for Theroux at her mansion in Bel Air, Calif.
