Justin Trudeau and Barack Obama's dinner together made the internet go crazy

Following a speaking engagement in Montreal, former President Obama took the opportunity to reunite with a friend: Justin Trudeau, Prime Minister of Canada.

According to Newsweek, the two had dinner together at Liverpool House. Trudeau shared a photo of the pair on Twitter:

"How do we get young leaders to take action in their communities," Trudeau wrote. "Thanks Barack Obama for your visit and insights tonight in my hometown."

The Obama Foundation also shared the photo and also mentioned their conversation:

"Tonight in Montreal, Barack Obama and Justin Trudeau discussed their shared commitment to developing the next generation of leaders," the foundation wrote.

Obama spoke at the Montreal Chamber of Commerce on Tuesday, where he criticized current President Trump for pulling out of the Paris climate deal.

He also urged attendees to not be afraid of the future "We're going to have to replace fear with hope," the former president said. "That's the spirit that we need right now."

Some observers on social media believed that Obama and Trudeau spoke about Trump during their dinner -- and that they were trolling him:

Mostly, though, observers were happy their bromance is alive:

Obama and Trudeau have a long-standing friendship.
