It looks like Jennifer Aniston may have someone on her side following her shocking spilt from her husband, actor Justin Theroux. 

The former couple's neighbor claims that Theroux was the "devil" and that he made Aniston's living experience in New York City a "living nightmare."

Aniston's Separation Drama 

Theroux's neighbor, Norman Resnicow, said that Theroux's apartment had severe water damage that actually seeped into his living room. Resnicow also stated that Anison was always nice to him but Theroux was "crummy" towards him and treated Aniston the same. 

"Everyone knows Jennifer hated the place," Resnicow stated

The man continued that he is "rooting" for Aniston as the actress named her dog after him. Resnicow is also pursuing legal action against Theroux for the alleged water damage. 

Where It All Began

Details of the couple's troubled marriage made headlines after the pair announced their decision to separate after two years of marriage.

"In an effort to reduce any further speculation, we have decided to announce our separation. This decision was mutual and lovingly made at the end of last year. We are two best friends who have decided to part ways as a couple but look forward to continuing our cherished friendship," the couple released in a joint statement.

Since then, reports and rumors began to suggest that the couple were never even married and had been living apart for "quite some time."

In addition, it was speculated that Theroux may have been unfaithful to Aniston and that the couple tried to have a baby but it didn't work out

The couple began dating back in May 2011. In January 2012, the two purchased a home together in Los Angeles' Bel-Air neighborhood for about $22 million dollars. Aniston married Theroux at their Bel-Air estate in August 2015.

Prior to this, Aniston was linked to actor Vince Vaughn from 2005 to 2006 and to singer John Mayer from 2008 to 2009. Aniston's first marriage was to actor Brad Pitt, whom she began dating in 1998. Pitt and Aniston were married from 2000 to 2005.

Rumors of Pitt's infidelity began to swirl after the actor was seen with his Mr. and Mrs. Smith co-star, Angelina Jolie. Though Jolie and Pitt didn't confirm nor deny the rumors, the couple went on to have three children together before tying the knot in 2012.

Pitt and Jolie separated in 2016.

Theroux was in a relationship with stylist Heidi Bivens for 14 years until 2011 before getting linked with Aniston.
