Rege-Jean Page and Phoebe Dynevor both had "horrendous coffee breath" during their 'Bridgerton' sex scenes.
The 34-year-old actor has revealed that he and his 27-year-old co-star had strict rules in place before shooting their intimate scenes - but they're also huge fans of drinking coffee early in the morning.
During an appearance on 'The Late Show with Stephen Colbert', Rege-Jean explained: "What no one knows about 'Bridgerton', [was that] Phoebe and I had horrendous coffee breath the whole way through."
The actor revealed that he and Phoebe struck-up an agreement before shooting their sex scenes.
He shared: "You approach your other actor and go, 'Hey, so the scenes after lunch, what are our rules? Are we no onions? Are we no garlic? Do I have to get the coffee in early?'
"We both are like, 'I actually really like coffee so I don't mind.'"
Meanwhile, Phoebe previously admitted that they "both drink a lot of coffee".
The actress also revealed that her co-star smells "really, really nice".
Asked how Rege-Jean smells, she replied: "Why have so many people asked me that? He smells really, really nice. He never, ever had bad breath, and he doesn't smoke or anything like that.
"We both drink a lot of coffee, so sometimes we both smell like that, which was fine. He's unscented in a good way."
What's more, Phoebe admitted that she loved working with Rege-Jean on the Netflix show.
She said: "I think we worked really well together, and I learned a lot from him.
"We have different acting styles, so we bounced off each other in that respect. We both were on the same page about the characters and what their relationship was. I loved working with him."
