Who needs a white Christmas?

Jennifer Aniston and fiancé Justin Theroux spent Christmas Eve working on their enviable tans while vacationing in Cabo San Lucas, Mexico.

The Friends star has a tradition of ringing in both Christmas and New Year’s on the beaches of Cabo and has spent previous years there with pals Chelsea Handler, Courteney Cox and even former beaus John Mayer and Gerard Butler.

Aniston was spotted taking in the rays while sipping a cocktail and reading a book next to Theroux who seemed more apt to take a light snooze during his tanning session.

The Horrible Bosses actress looked as fit as ever in a magenta string bikini — which helped to dispell rumors that she is pregnant with her first child.

The 43-year-old is known for her killer figure, especially in a bikini, made possible in part to her longstanding dedication to yoga (and good genes).

Her bod is so fierce that Celebuzz ranked her as one of the top 101 Best Bikini Bodies of All-Time.
