During their tropical holiday in Mexico, onlookers cannot help but wonder whether Jennifer Aniston and Justin Theoroux are on the verge of breaking up. What's supposed to be a romantic getaway appears to be a distant and awkward affair for the couple. According to eyewitnesses, Jennifer Aniston and Justin Theroux appeared to purposely ignore each other though seated side by side in the hotel's deck.

Furthermore, the 'We're the Millers' actress appeared to interact more with her friend Courtney Cox. While the two have previously expressed their plans to tie the knot, no official wedding date was confirmed yet. If Jennifer Aniston and Justin Theoux's breakup will soon take place, the long distance between the two might be one of the reasons. The blonde beauty is oftentimes in California whereas her husband-to-be is in New York.

According to sources close to the two, Aniston and Theroux have decided to take things slowly: "Jen and Justin have hit a rough patch. Right now, there are no wedding plans, no baby plans and no more buying houses together."

"Most of Jen's friends expected this to happen because she's usually with guys for two years at the most before they break up," claims another insider.

The couple is currently staying with a group of friends in the luxurious beachfront home Casa Oliver where one night reportedly costs $9,500. 

Will the couple eventually hit Splitsville or are they merely not in the mood to publicly show their affection for each other?
