Jennifer Aniston Engagement News: Actress and beau Justin Theroux Calling it Quits?

Whenever Jennifer Aniston and fiancé Justin Theroux are not spotted together, the break up rumor mill starts churning real fast.

The latest rumors are claiming that Aniston ended the engagement with her beau. Radar Online reported last month that Aniston confronted another woman about Theroux, which caused her to cancel the engagement.

"Justin was humiliated and embarrassed by Jen's crazy behavior," an insider said. "Especially considering the fact that their relationship is hanging by a thread, he couldn't believe that Jen would go so far as to confront the girl about it. They had a huge fight over the phone."

Gossip Cop, however, is reporting that the rumors are "typical garbage." Theroux has been incredibly busy with his shooting schedules, which explains why he has not been seen with Aniston. Theroux has been flying between Austin, Texas and Rome to film the second season of HBO's "The Leftovers" and "Zoolander."

Meanwhile, Aniston has been hanging out with her friends in the States. She most recently was seen meeting J.J. Watt, the defensive end from the Houston Texans.

"It was incredible," Watt told Us Weekly. "She was so sweet. She was awesome. Everybody has kind of known for a long time that she was the one person that I've wanted to meet... And she was really sweet and awesome and I'm thankful that she was so cool because I was not."

The last time that Aniston and Theroux were seen together was back in April when they attended Robert Downey Jr.'s birthday party. Aniston gushed about Theroux to PEOPLE in June.

The "Cake" actress said, "He's the best thing this decade."

The couple met on the set of the 2008 movie, "Tropic Thunder." They co-starred in the 2012 movie, "Wanderlust." Theroux proposed that same year.
