Aniston, 44, rocked a muy caliente beach vibe in a tiny red bikini and matching wrap, showing off her toned tummy and sculpted arms as she shared poolside kisses with a gallant and equally fit Theroux, 42, who lovingly wrapped her up in a towel after a dip.
Aniston, who has been busy promoting her most recent film, We’re the Millers, looked relaxed as speculation of a wedding date continues.
She wore her long hair up in a cool ponytail as the pair lounged in the sun and held each other close.
