Proof Even Jennifer Aniston's Friends Have No Idea When Her Wedding Is

— -- Jennifer Aniston said even her friends get fooled by all the rumors that the actress and fiance Justin Theroux are tying the knot on certain weekends, according to various media reports from time to time speculating when the two will wed.

While on the "Ellen DeGeneres Show," which airs today, DeGeneres said "because it is so secretive ... when we're invited, we go, 'We can't be in town, but should we be in town,'" referring to the fact that they don't know what to believe.

In fact, actors and couple Sacha Baron Cohen and Isla Fisher were also fooled.

"Our friends Sacha and Isla showed up for four parties, four little gatherings, about a year ago, they would show up in beautiful wedding wear," Aniston, 45, revealed. "Even the Fourth of July last year, they showed up and Sacha was in a powder blue suit and Isla was in a little cute dress and we were like, 'Guys, it's the Fourth of July, we are in cutoffs, we are eating hot dogs, we will actually let you know.'"

She continued, "Like Thanksgiving, I had a friends who said, 'I can't come this year, but should I?'"

DeGeneres, 56, even said one time her wife Portia de Rossi were told there may be a thing hosted by Aniston, but it wasn't like "Just come over, it was like, 'We'll let you know where it is and what time.'"

"We were like, 'Oh, should we make that?" DeGeneres said.

"But you didn't come," Aniston said.

"Yeah, we found out we didn't need to!" DeGeneres laughed. "There has to be a wedding for me to stay in town."
