Robert DeNiro took being petty to a new level when he snubbed Arnold Schwarzenegger a Beverly Hills gala.

“If you’re supporting Trump, I want nothing to do with you,” DeNiro said at the Friends of the Israel Defense Forces Western Regional Gala on Thursday after he refused to take a photo with Schwarzenegger, Variety reported.

DeNiro apparently didn’t do his homework as Schwarzenegger, as the former governor of California announced in October that he won’t be voting for the Republican presidential candidate.

As proud as I am to label myself a Republican, there is one label that I hold above all else – American. My full statement: pic.twitter.com/biRvY8S3aZ — Arnold (@Schwarzenegger) October 8, 2016

The media managed to take some pictures of the two before DeNiro walked away, according to Variety.

“Are you voting for Trump?” the “Goodfellas” actor continuously asked Schwarzenegger before he walked off.

Schwarzenegger, while stating he won’t vote for Trump, has not said who he will vote for.

“If you’re not part of the solution, then you’re part of the problem,” DeNiro said as he walked away.

It’s not the first time DeNiro has acted like a child during this election.

A month ago he went into a tirade about how he wanted to punch Trump in the face while doing a video to encourage people to vote.

DeNiro could have made the incorrect assumption about his fellow actor from a fake Clint Eastwood account on Twitter that gained over 6,000 retweets and 8,000 likes after announcing that both he and Schwarzenegger had early voted for Trump.
