Justin Theroux and Jennifer Aniston took 'make or break New Year holiday' before split

Jennifer Aniston and Justin Theroux reportedly made a last ditch attempt to save their marriage by taking a New Year's holiday to Mexico.

The celebrity couple announced their split on Thursday, saying that the decision was “lovingly made” and that they would remain good friends.

Pictures of the pair on New Year’s Day have emerged, showing them holidaying with Jason Bateman and his wife Amanda Anka in Cabo San Lucas, Mexico.

And, now, sources claim that the trip was a “make or break” getaway for Aniston and Theroux.

An inside told Us Weekly: “Jason Bateman’s wife convinced Justin to go to Cabo. She has been the mediator in recent months, trying to get Jen and Justin to work through their problems and save their marriage.

“The Cabo trip was a make or break vacation for Jen and Justin. They went away with their friends hoping to have fun and work on it.”

But the source added: “The guys and girls hung out separately in Mexico. It didn’t work.”

Standard Online have contacted representatives for Aniston and Theroux for comment.

The pair tied the knot in a private Los Angeles ceremony back in August 2015, having been together for four years after meeting on the set of Wanderlust.

In a joint statement, they said: “We are two best friends who have decided to part ways as a couple, but look forward to continuing our cherished friendship.

“Normally we would do this privately, but given that the gossip industry cannot resist an opportunity to speculate and invent, we wanted to convey the truth directly."
