Jennifer Aniston is delaying her wedding to Justin Theroux after it conflicted with ex-husband Brad Pitt's wedding to Angelina Jolie, US Weekly reports. The former Friends star is said to have hit a steel wall in her plans to wed actor and screenwriter, Justin Theroux, and that wall comes in the form of her former husband, Brad Pitt, and his plans to wed his own fiancé, Angelina Jolie, this summer.

The 44-year-old Horrible Bosses star has pushed back her own wedding date because Pitt and Jolie, who already have six kids together, have scheduled their ceremony for this summer and she wants to avoid any preconceived overlap with her A-list former husband. 

A source tells US of Aniston on Pitt and Jolie, "She does not want her day associated with them." Initially, it was said that Aniston was in a rush to get married before Pitt and Jolie tied the knot this summer, but "Justin got weirded out by all the rushing," the source said. So, the two have put their marriage plans on the backburner, and "Nothing has happened on that front in a month," the same source told US. 

Aniston hasn't been resting on her laurels in the meantime, though. She recently finished wrapping the Untitled Elmore Leonard project, and she's been busy with Theroux redecorating their $21 million Bel Air mansion. 

The stress from the wedding planning may have gotten to her a little bit, so easing into a later date might help alleviate some of the tension that's come with the marriage plans. 

The same insider told US,  "She has been cranky from this stress," and "Justin's never seen her like this."

Pitt famously started dating Angelina Jolie just months after his split with then-wife Aniston, in 2005. Since that time, the World War Z star has adopted two children with Jolie, and Jolie has given birth to their daughter, Shiloh, and twins, Knox and Vivienne for a grand total of 6 progeny for the A-list pair. 

Aniston hasn't been married since her divorce from Pitt, but she's dated a host of different men, including Vince Vaughn and John Mayer. In May 2011, she began seeing Justin Theroux, who was famously separated from his wife at the time. 

In August 2012, Aniston and Theroux announced they were engaged after purchasing the Bel Air mansion in January of the same year. The engaged couple do not have any children together, but pregnancy rumors have swirled around Aniston for years as the actress has said many times she'd like to be a mom. But recently, she's capitulated a bit and the 44-year-old actress says she just wants a happy marriage first, and doesn't think children are necessary for that happiness.
