Julia Louis-Dreyfus finally answers question Seinfeld fans have been asking for decades

EXCLUSIVE -- "I can't possibly tell you that!"

There's one question about the Seinfeld finale that fans have pondered for decades, but Julia Louis-Dreyfus isn't willing to give up the answer.

In the iconic '90s sitcom's last episode, Louis-Dreyfus' character Elaine appears to nearly confess her love to Jerry Seinfeld, blurting out, "Jerry, I've always loved..." before she stops.

Viewers have long debated what she was going to confess in that moment, and only a handful of people in the world know the answer.

Sadly, I am not one of them.

"Ohhh," Louis-Dreyfus replied after I asked the question, "It's supposed to be a secret!"

And that, she says, is the point: There was never meant to be an answer, and there probably never will be.

Seinfeld, widely recognised as the biggest sitcom of all time, began in 1989 and ran for nine seasons and 180 episodes.

Years after it aired, parts of the 75-minute finale are still a topic of discussion for fans.

The series ended with Elaine, Cosmo Kramer, Jerry, and George Costanza being sentenced to jail for a year after failing to help a stranger who was carjacked at gunpoint.

The ending was widely debated, with some saying it ruined the show, while others said it was satisfying to see the group finally face the consequences of their bad behaviour. 

Louis-Dreyfus said despite the rampant debate around the finale, she had no regrets.

"I know it was controversial, which is nice, that's a good way for us to go out ... I know it wasn't satisfying for some people, it was for others," she told nine.com.au.

"I have no complaints, let's put it that way."

For over three decades, Louis-Dreyfus has been one of Hollywood's wittiest leading ladies, rising to fame with her role as Elaine.

She was just 28 when she was thrust into the spotlight, becoming a household name overnight.

Yet despite her hugely successful career, she admits there's one aspect of her job she is still working at.

"A lesson that I try to keep learning is to trust my own instincts. Sometimes that can be hard, you question yourself when you shouldn't," she admits.

The comedy legend's latest project is a family film called The Sheep Detectives, featuring Australian Hugh Jackman and Irish comedian Chris O'Dowd. 

Louis-Dreyfus and O'Dowd take the comedic leads, voicing CGI sheep Lily and Mopple, who try to solve the murder of their shepherd George, played by Jackman.

The pair weren't in the same room while they recorded their respective parts, but you'd never know that from watching the film, which is a testament to their comedic genius.

"We did this from an isolated soundbooth, we did this on our own, they put it together," Louis-Dreyfus said.

"If we got another shot at this is would be fun to do it together ... Chris and I only met for the first time yesterday, believe it or not!"

Seeing the disbelief on my face, O'Dowd chimed in, "I think they just hope that people are playing on the same frequencies with these things, and I think we probably did."

The Bridesmaids star added that acting with only your voice is a different feeling from acting on screen for both of them. 

"Vocally, when you're doing animated work, it's the difference between singing in front of people and singing in the shower, when it feels really good," O'Dowd said.

"It's like you're singing in the shower, and you're letting yourself go, with the best of it being captured."

Louis-Dreyfus smiled and chuckled in agreement.

The Sheep Detectives is out in cinemas across the country on May 8.
