Jennifer Aniston has been flaunting her body for nearly a week in a series of barely-there bikinis while on a Mexican holiday with her fiancé Justin Theroux and friends, but one specific swimsuit almost left her fully exposed.

While relaxing by the pool in a turquoise-colored two piece Monday, Dec. 30, the 44-year-old removed the straps of her top to get an even tan. The actress exposed a large amount of cleavage as a result.

Jennifer Aniston and Justin Theroux 'Can't Keep Hands Off Each Other?'

Aniston has been in Mexico with her fiancé as well as Friends co-star Courteney Cox, Jimmy Kimmel and his wife Molly McNearney. Shock jock Howard Stern and his wife Beth Ostrosky also joined them.

While the former Friends star and Cox, 49, showed off their bikini bodies on the trip, Aniston and Theroux put rumors of them separating to rest when they showed each other affection on the trip.

Mexico is a common jaunt for the Horrible Bosses star, who has taken trips to the area frequently over the years with different groups of friends, especially during the holidays.

Last year, just a few short months after announcing their engagement, Aniston and Theroux took the same trip to Mexico with Kimmel and McNearney, as well as fellow actors Emily Blunt and John Krasinski, who are currently expecting their first child together.

Aniston has also been spotted on Mexican vacations with her friend and comedian Chelsea Handler.
