Ashton Kutcher admits he and Natalie Portman made the same film as Mila Kunis and Justin Timberlake

Ashton Kutcher has admitted he and Natalie Portman made 'basically the same movie' as his now-wife, Mila Kunis, and Justin Timberlake.

You know the one I'm talking about - the one where two friends decide to make their relationship more physical without any of the commitment or romance typically expected between couples. The one released in 2011? Oh, right, that still doesn't really narrow it down.

Kutcher's version of this particular movie was called No Strings Attached, with a synopsis that explains: "A guy and girl try to keep their relationship strictly physical, but it's not long before they learn that they want something more."

He reminisces on the experience while reuniting with his co-star for a workout:

The same year, Kunis starred in Friends With Benefits, which is described as follows: "A young man and woman decide to take their friendship to the next level without becoming a couple, but soon discover that adding sex only leads to complications."

You have to admit, those descriptions are interchangeable.

Kutcher himself admitted to the similarities during an episode of his series Our Future Selves, where he reunited with Portman for a joint Peloton workout.

During their session, Kutcher recalled how he and Portman first started 'hanging out' during the filming of Friends With Benefits - wait, sorry, I mean No Strings Attached - with Portman adding: "Who would've thought 20 years later, we'd be on a Peloton together?"

Kutcher, who married Kunis in 2015, then commented: "Wait, it's also weird because my wife was shooting basically the same movie, called Friends With Benefits."

Both films proved successful, earning $149 million each worldwide, though Kunis' appears to have gone down a bit better with filmgoers as it scored a Rotten Tomatoes audience score of 65 percent, compared to Kutcher's 51 percent.

So, we had Kutcher and Portman getting up close and personal for No Strings Attached, and Kunis and Timberlake doing the same for Friends With Benefits, with Kutcher and Kunis later tying the knot in real life after previously having had an on-screen relationship in That 70's Show.

The connections don't stop there, however, as Portman reminded Kutcher that she and Kunis had just finished filming Black Swan together at the time, in which their characters were entangled in knotty sexual drama, saying: "So we were all making out with each other."

Kutcher is of course not the only one to pick up on the fact that Friends With Benefits and No Strings Attached share a lot of similarities, but Twitter users have shown their support for both and made clear there's room for all sorts of complicated relationships on the big screen.
