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

Aniston says friends often wear wedding outfits to her parties, just in case.

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.

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

"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."
