It was very much business as usual for the pair as they got on the promotional trail for their film Focus in Argentina.
Will – who stepped out in a vibrant yellow jumper - looked relaxed and at ease as he posed side by side with 23-year-old Margot.
The pair had their arms around each other's backs in a group lineup at a press call in Buenos Aires with actors Gerald McRaney and Rodrigo Santoro.
If Will has been upset about rumours he and Margot are more than just friends, he certainly wasn't showing it – smiling widely for photographers.
Their friendship was questioned when the photos of them surfaced, with reports Will's marriage was under strain.
Margot denied that anything untoward had gone on, however, saying on Twitter that she and 45-year-old Will had been just " goofing around".
She wrote: "Been working non-stop, just catching my breath. There's absolutely no truth to the ridiculous rumor…"
"...It's disappointing that goofing around on set could be taken so out of context."
