The Friends alum, who has been engaged to boyfriend Justin Theroux for over two years, admits her pals are constantly on the lookout for hints that a low-key gathering they've been invited to is actually a cover-up for their big day.

Aniston chatted about her wedding day excitement with Ellen DeGeneres during an appearance on her talk show which airs later today, Tuesday, Nov. 25. And even though the duo are good friends in real life, the talk show host admitted the constant speculation has her and wife Portia de Rossi on permanent high alert.

"I am your friend and I know a lot about you, but if I weren't your friend, I have to discuss the crazy constant rumors of the wedding," DeGeneres said, introducing the topic of marriage to the conversation.

"I know that I'll know when the wedding is, but sometimes, because it is so secretive, when we're invited [over] we're like 'I'm not in town....but should we be in town?'" she continued.

Aniston admitted it was a common concern! "Our friends Sacha [Baron Cohen] and Isla [Fisher] showed up for four little gatherings, about a year ago, in beautiful wedding wear. Even for the Fourth of July last year, Sacha was in a powder blue suit, and Isla was in a little cute dress and we were like, 'Guys, it's Fourth of July, we were in cutoffs, eating hot dogs. We will actually let you know!'"

The 45-year-old actress revealed the questioning gets even worse around the holidays.

"For Thanksgiving, a friend of mine said, 'I can't come this year, but should I?'"

DeGeneres understood the dilemma. "That one time that Portia and I called, and it was very secretive, like there may be a thing this weekend, we'll let you guys know where it is, and what time. And we were like, 'Oooh, should we make that?'" the show host recalled.

"But you didn't come," Aniston added, laughing.

"We didn't come because we didn't need to," agreed DeGeneres, cracking up. "I'm very busy. There has to be a wedding for me to stay in town!"
