Cheating? Actress’ steamy PDA with her co-star causes a stir

Actress Margot Robbie has supposedly been in a relationship for the last seven months, but it certainly didn't seem that way over the weekend.

The Wolf of Wall Street star was spotted getting very cosy with actor Alexander Skarsgard during a recent event at the Sundance Film Festival in Utah, where Margot is promoting her upcoming film Z for Zachariah. 

The pair met on the set of Tarzan, which comes out next year, but onlookers said they definitely looked like more than just co-stars during a night of partying on Friday.

Margot and Alexander were seen sitting together at a 10AK Tinder party looking seriously cosy. "They were there late-night holding hands. Margot and Alexander definitely looked like a couple," an eyewitness told E! News. "They were very touchy-feely and at one point were full on kissing."

Despite the apparent PDA on Friday, Margot has been seeing film director Tom Ackerley for around seven months, since the pair met together on the set of Suite Francois.

No reports of a split have emerged – in fact the couple even holidayed in Margot's native Australia together over the festive season, with Tom spending Christmas at Margot's family home in Queensland followed by two weeks of touring the Gold Coast.

Although Margot kept quiet about the trip on her own social media accounts, Tom posted a number of pictures on Instagram throughout his visit.

For his sake we really hope the reports of Margot's cheating are untrue!
