There have been rumors about a nightclub hookup between Margot Robbie and Alexander Skarsgard, who both co-starred in Tarzan.

The Wolf of Wall Street bombshell Margot Robbie and True Blood hunk Alexander Skarsgård have fuelled relationship rumors after the gorgeous celeb duo was seen getting extra close at a recent Sundance Film Festival event.

The source for the magazine claims that Alexander, 38, and Margot, 24, began their evening at the Sabra Hummus Kickoff Party and afterwards went to the 10AK pop-up bar where they “arrived and sat together.”

The source also divulged that, ‘the couches there are not big at all.’

But it was a bystander who observed their night out develop into something much more.

“They were there late-night holding hands. Margot and Alexander definitely looked like a couple,” an eyewitness told the site of the two at the 1Oak Tinder Party Friday.

“They were very touchy-feely and at one point were full-on kissing.”

In David Yates’ Tarzan, set for release in July 2016, Robbie and Skarsgrd co-star opposite one another. Samuel L. Jackson, Christoph Waltz, and Dijimon Hounsou also appear in the movie.

The two also joined stars Chris Pine and Chiwetel Ejiofor at the Sabra Hummus Kickoff Party earlier in the day.

“They came separately but left together in a big group,” a source told People.

“Alex told the girl at the door he was coming to see his ‘friend.’ They asked who his friend was and he said Margot Robbie … he came to see her.”

Margot and Alexander had a red carpet moment at the Kickoff Party before the alleged kiss.

They were both dressed in winter warmers, and by putting an arm over each other, they helped each other stay warm.

Margot is presently promoting her forthcoming movie Z for Zachariah while attending Sundance for the first time. Robbie plays a young lady who, after a catastrophic nuclear incident, thinks she is the only survivor—until two strangers unexpectedly show up on her property in the woods.

Tom Ackerley, the assistant director on the actress’ 2014 film “Suite Francaise,” and they just spent the Christmas season together in Australia.

Margot played tourist for her assistant director lover by bringing him to the Whitsundays and Byron Bay after spending Christmas with her family in Queensland.

She and Tom looked like any other young couple as they shared a glimpse of their adventures via Tom’s Instagram account.

Back in November, the dashing designer shared a photo of himself and Margot acting out the iconic elevator scene from Dirty Dancing with the comment, “#Nooneputsbabyinthecorner.”

The pair was photographed together at a Rangers game in November.
