This may be the last Instagram post we see of Brie Larson and Jacob Tremblay together.

Likely not, seeing as the Room co-stars are also self-proclaimed best friends, but Larson did post a sweet tribute to the 9-year-old actor as they wrapped their final press appearance in Japan.

"28 weeks ago (according to Instagram) Room premiered at the Telluride Film Festival," she wrote. "After the screening @jacobtremblay and I toasted. He had chocolate milk and I had red wine. I remember feeling so vulnerable after sharing this movie with the world for the first time; unsure of what was to come. Last night marked what may be our final toast to this film. He had a soda and I had sake."

"Together we have traveled the globe, spent almost two years hanging out, playfully arguing about things like who can hold their breath longer and talking at length about Room," the Oscar-winning actress added. "At its core, every step of the way has been taken with love."

"We were generous and patient with each other. We laughed a lot, especially when it was hard. We picked each other up, answered for the other when one was tired and always kept silliness alive. Thank you Room for bringing us together. Thank you Room for uniting us with the rest of the world. Thank you to everyone who shared this journey with us. I will never ever forget it," she concluded.

Here's that first toast chocolate milk and wine toast, just about seven months ago:

"Thank you Brie! I have had so much fun with you! #byebyeroom #bff #bestcoworker," Tremblay posted on his Instagram.
