Florence Pugh has seemingly revealed that her We Live In Time co-star Andrew Garfield, who isn't publicly on social media, may have a private X (formerly Twitter) account.

While being quizzed on how well they know each other in a Vanity Fair feature, 28-year-old Florence was asked which social network is 41-year-old Garfield's favorite.

Clad in an off-the-shoulder white eyelet dress, she answered, 'Well, you don’t have any public social network, but the ones that you do, that I do know of you using, you tweet. Not much, but you do do twits.'

Garfield then corrected her: 'I've never tweeted.'

After the cat was out of the bag, the Don't Worry Darling actress replied, 'Oh, I’m sorry — but you do look at twits a lot.'

Andrew then added, 'You were right the first time — no social network!'

Finally, Pugh caught on and said, 'Oh, so I shouldn’t have said that.'

The actor notably portrayed Eduardo Saverin in the 2010 film The Social Network, which was about the inception of Facebook.

Florence's slip-up comes after her co-star revealed that a sex scene in their upcoming movie went on a tad too long.

The Spider-Man star appears as Tobias Durand in the rom-com, with the actress appearing as his love interest Almut Brühl.

During an appearance at 92nd Street Y in New York City, he told the crowd: 'The scene becomes passionate, as we choreographed it.

'And we get into it as it were, and we go a little bit further than we were meant to because we didn’t hear "cut" and it’s feeling safe. And we’re just kinda like, "Ok, we’ll just go into the next thing, we’ll let this progress, and we’ll just carry on."' 

Andrew added that he and Florence continued performing the intimate sequence for such a long time that it forced the camera operator to turn away.

He explained: 'At a certain point, both of us, we’re both kind of telepathically saying to each other, "This definitely feels like a longer take."

'I look up, and in the corner is Stuart and our boom operator. Stuart has the camera by his side and he’s turned into the wall.'

We Live In Time follows the 'unconventional' love story of a recent divorcée and an on-the-rise chef.

The romantic comedy from A24 will be released in theaters on October 11.
