Leo Woodall and Meghann Fahy, who star together in The White Lotus, are rumoured to be dating after fans spotted a flirty Instagram exchange between the two of them.
Meghann told Leo that she "loved" him and he said that he "loved her right back" in one of their many cute messages to each other.
The rumours were first sparked after gossip site DeuxMoi suggested the pair were an item, which then led fans to channel their inner Sherlock Holmes - uncovering the public messages between the actors.
Leo, 26, plays cheeky but troubled chap Jack, while Meghann, 32, is the care-free Daphne.
In September Leo shared a collection of photos of the cast on Instagram, and captioned them "That's amore".
There were several photos of Leo and Meghann together in the dump, as well as ones of her on her own.
Meghann replied: "I love you! I love these! I love you!" accompanied by a kissing and winking emoji.
Leo then replied to her comment: "Love you right back," with a heart emoji.
One of the photos was Meghann posing in front of a sculpture that reads "f***", wearing shorts and leaning on a scooter.
Another was the pair cuddling after what looked like a heavy night.
Leo was also spotted commenting on Meghann's Instagram after she shared a selection of photos from Elle UK.
"And thank you @elleuk," she wrote in the caption, "I love the UK and I love all of the Elles!!!"
"UK loves you back," commented Leo, which she replied with a lovestruck emoji.
"Meghann and Leo are 1000 percent [dating]," declared the tipster for DeuxMoi.
"Tons of witnesses. Not a whole lot of secrecy behind this pairing."
The account's podcast Deux/U, they read an anonymous email which suggested that the pair had even gone on a holiday together after the show had wrapped.
Theo James, who set pulses racing after stripping off to nothing but his birthday suit in the first episode, dropped a few hints into the relationship of the cast.

"We had a great time. We were in Sicily and Rome for six and a half months. The show is about unfettered hedonism, in some ways, so there was a little bit of embracing that."
"It's a massive cast," Theo explained, "so not every person is going to be kissing and high-fiving each other, but we definitely had a lot of fun."
Theo, who confirmed recently that he wore a prosthetic penis after fans went wild, plays Meghann's alpha-male husband.
