Netflix's steamy Regency-era series Bridgerton has made it into Ashton Kutcher and Mila Kunis's bedroom.

Ashton, 42, revealed that he thought he caught his 37-year-old wife 'watching a porno' in the middle of the night only to learn she was just catching up on a particularly sexy scene of Bridgerton. 

The couple laughed off the understandable confusion during a virtual chat with Hoda Kotb and Jenna Bush Hager on the where they were promoting their new Cheetos Super Bowl commercial.

'So, I'm on episode five for anyone who's seen it, y'all are aware what happens in episode five,' Kunis told Hoda and Jenna to set up the story.

Fans of the 19th century dramedy will recall that things really start to heat up in the bedroom between the Duke of Hastings and Daphne Bridgerton.  

Mila continues: 'I fall asleep by 9:30, I am out. It doesn't matter what is on, I'm asleep. Last night, I clearly stayed up till midnight. I was like, "What's happening in this show?"'

'He wakes up in the peak of the fifth episode and this is a TMI, but he literally goes, "Are you watching a porno?" He was so confused.' 

Bridgerton is basically Jane Austen melded with Gossip Girl but it's sensual, graphic sex-scenes, particularly between actors Regé-Jean Page and Phoebe Dynevor, were all anyone was talking about after the series debuted on Christmas.

Ashton chimed in: 'She's watching in the middle of the night, and I didn't know what was going on. I was like, "Is there someone else in the bed?" It was terrifying!'

'I was like, "Shhh, be quiet, this is a wedding!"' Kunis quipped.
