In fact, the former Friends star says she still needs to find a dress.
"No, I don't," she exclusively told me at the premiere of Call Me Crazy—the new Lifetime movie about mental illness that she coproduced—when I asked if she had picked out a gown yet.
Aniston cracked that the wedding planning "might make me crazy."
For now, she's is concentrating on promoting her latest project, which premieres on Lifetime on April 20.
The movie, a series of five shorts dealing with various mental illnesses, is a follow-up to 5, a similar movie Aniston produced for the network about five women affected by cancer.
"Mental illness seemed to be [a topic] that a lot of us felt was an important one and touched a lot of our lives, a lot of our families lives," Aniston said.
"That seemed like one that needed attention because all of the stigma around it and the sort of shame around it."
