Ashton Kutcher and Natalie Portman filmed the same movie as Mila Kunis and Justin Timberlake.

Ashton Kutcher has revealed the worst hidden secret in the history of romantic comedies. For the September 20th debut of his series “Our Future Selves,” he and his “No Strings Attached” co-star Natalie Portman got back together for a Peloton exercise.

According to, during their session, the actor acknowledged that their 2011 romantic comedy was very similar to another film from the same year starring his now-wife Mila Kunis and Justin Timberlake.

After Ashton Kutcher added, “I suppose the first time we really began hanging out was when we did No Strings together,” Portman remarked, “Who would’ve imagined 20 years later, we’d be on a Peloton together?”

When asked further, Ashton Kutcher added, “Wait, it’s also odd because my wife was filming virtually the same movie, called ‘Friends With Benefits.'”

‘No Strings Attached,’ by Ivan Reitman, and ‘Friends With Benefits,’ by Will Gluck, are both about a man and a woman who decide to make their relationship sexual without becoming a loving partnership, only to find out that it’s more complex than they first believed.

Both movies did well in theatres. Box Office Mojo reports that No Strings Attached earned $70 million domestically, whereas The Heat only grossed $55 million.

Also, on Our Future Selves, Kutcher’s interview and marathon training series with Peloton, Portman brought up an interesting subject to her former co-star.

Mila and I had just finished working on the set of Black Swan. As a result, we were all passionately kissing one another.

In 2010, Darren Aronofsky’s ballet thriller, “Black Swan,” made over $329 million worldwide, more than twice as much as the rom-com.
