People are losing it after realizing Nicole Kidman has very racy sex scene with A-list best friend's ex in Netflix series

Nicole Kidman found out before filming a new Netflix series that she had to film raunchy sex scenes with her best friend's ex.

It turns out that Nicole Kidman and Liev Schreiber had quite an awkward situation to overcome before filming for Netflix's The Perfect Couple.

Fans are loving the new release, but a bit of behind the scenes info has made all those raunchy sex scenes feel a little... well, uncomfortable.

Fans were left with jaws on the floor after finding out that Schreiber is actually the ex-partner of an A-lister who happens to be 'besties' with Kidman.

The real life ex is none other than Naomi Watts, and the pair were in a relationship for 11 years.

They split in 2016, but did have two children together - Sasha, 17, and Kai, 15.

Now, eight years on from the split, Watts' pal is filming racy scenes with her former flame in the brand new Netflix series.

And it didn't take fans long to clock onto the vibes.

"Watching episode 1 of The Perfect Couple and suddenly remembered that Liev Schreiber, who plays Nicole's husband in the show was in a relationship with Naomi Watts, one of Nicole's closest friends. Like whoaaaa," one commented on X.

Another added: "Starting The Perfect Couple and just wondering the dynamic between Liev Shrieber and Nicole Kidman since that's is the bff of his ex wife (Naomi Watts)."

But one person did note that Kidman made a nice gesture to Watts before she took on the role.

One fan revealed: "The fact that Nicole asked Naomi if it was ok to ask Liev Schreiber to be her husband in The Perfect Couple and she was like... of course!"

Talking to Entertainment Weekly during the Toronto International Film Festival, Watts said: "We always check in, we're besties. That was very kind of her to do that."

Despite admitting she hadn't watched the series yet, her best friend seemingly getting it on with her ex isn't going to bother her enough not to tune in.

She said: "I'm desperate to [watch] because everyone is raving about it.

"It just launched, what, two days ago. I'm very much looking forward to it. I have seen the trailer. It looks fantastic."

Despite fans clocking onto the 'uncomfortable' vibe during the racy scenes, director Susanne Bier has actually explained it was intentional.

Speaking to the Metro, she said: "It's sort of a little bit of an uncomfortable sex scene in there. It doesn't feel entirely mutual in a way.

"But also, it was very conscious. We understand exactly what's going on."
