Tarzan and Jane forever!

Alexander Skarsgard and Margot Robbie have been hitting up the party scene at the Sundance Film Festival.

The stars of the upcoming Tarzan movie got things started at the Sabra Hummus Kick-Off Party on Friday. Skarsgard, 38, met up with the actress, 24, who was “holding court with an entourage” that included Chris Pine and Chiwetel Ejiofor.

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

The pair then moved on to the 1OAK pop-up a little after 11:30 p.m.

“They arrived together and sat together,” says a source who was at the Tinder and VO|CO sponsored event. “And the couches there are not big at all.”

The pair were also planning to attend the Freixenet hosted Art of Elysium Party together Saturday evening, but Robbie was a last-minute no show.

The True Blood hunk instead roamed the bash with Bel Powley, his costar from the upcoming movie The Diary of a Teenage Girl.
