First Daughters have to stick together!

While attending their first-ever State Dinner on Thursday, Malia and Sasha Obama got the chance to meet Ryan Reynolds – and, in the process, shared what might be their cutest sister moment ever.

A picture from the receiving line shows Reynolds chatting with a seemingly starstruck Sasha. In the background, supportive big sis Malia, 17, shoots Sasha, 14, a grin and two thumbs up.

The Internet has been collectively “aww”-ing since the adorable pic was released, with people split between recognizing their own love for Reynolds in Sasha’s fangirling and praising Malia for cheering on her sister’s exciting moment.

At the state dinner, which was held in honor of Canadian Prime Minister Justin Trudeau, President Obama reflected on how his (glamorously dressed) daughters have grown up since he took office.

“When I was first elected to this office, Malia was just 10 and Sasha was 7. And they grow up too fast,” he said. “Now Malia is going off to college … And I’m starting to choke up.”

Trudeau, who knows what it’s like to be the child of the head of a country himself as the son of former Canadian Prime Minister Pierre Trudeau, also addressed the girls at the dinner, praising their impressive composure.

“I admire you very much, both of you, for your extraordinary strength and your grace, through what is a remarkable childhood and young adulthood that will give you extraordinary strength and wisdom beyond your years for the rest of your life,” he said. “The one thing that you have received from your extraordinary parents is the tools to be able to handle the challenges and the opportunities in front of you.”
