That's Margot Robbie's response to speculation that's been swirling ever since suggestive photos of her and Will Smith, taken in a photo booth, emerged this week.
"Been working non-stop, just catching my breath. There's absolutely no truth to the ridiculous rumor," the Australian actress wrote on Twitter.
She adds: "It's disappointing that goofing around on set could be taken so out of context."
That echoes what an insider told PEOPLE on Thursday – that Robbie, 23, and Smith, 45, "are just friends and were just being silly" by baring their chests in a photo booth on the set of the movie Focus.
Smith has not commented publicly on the controversy. But the source told PEOPLE that the incident poses no threat to Smith's relationship with wife Jada Pinkett Smith, saying: "Will and Jada's marriage is fine. Everyone there knows it was nothing."
