Is Justin Theroux jeopardizing his wedding to Jennifer Aniston as he buries himself in work?

Justin Theroux is back on HBO's "The Leftovers," which is going on its second season now. And Just Jared reported that Jennifer Aniston's fiancé will also be on board "Zoolander 2" with Ben Stiller and Owen Wilson as he was spotted in Rome on April 1.

"The 43-year-old writer/director and Ben, 49, were seen with lots of other crew members on the set," the report said. "The plot of Zoolander 2 is reportedly: Derek (Stiller) and Hansel (Owen Wilson) are modelling again when an opposing company attempts to take them out from the business."

Although they have been engaged for a long time, Jennifer Aniston and Justin Theroux have yet to set a wedding date.

Rumors were flying around that Jennifer Aniston and Justin Theroux are splitting up because of their busy schedules, as well as disagreement on their prenup.

In an interview with Deadline, Justin Theroux weighed in on the life inside a fish bowl while in a relationship to Jennifer Aniston.

"It's almost like you have this avatar running around in the world who's the most dramatic person on the planet, and everything is going right or wrong for that avatar," he said.

"And you can either pay a lot of attention and get really frustrated, or you can sit back and laugh and have a chuckle, you know, as you pass the magazine stand in the airport and go 'Oh, I didn't know that was happening,' which is, I think the better way to deal with it."

However, the July 20 issue of Life & Style magazine, as shared by Celebrity Dirty Laundry, claimed that the wedding of Justin Theroux and Jennifer Aniston already happened, and Grammy winner Ed Sheeran even sang at the ceremony.

The article alleged, "Despite failing to come to an agreement on a number of important issues - like having kids and where they will permanently live - the dup hashed out a last minute $170 Million prenup, gathered their closest A-List friends, and said personalized 'I Do's' on a sunny Southern California afternoon."
