Golden Globes: Jacob Tremblay Hops on Chair to Cheer 'Room' Co-Star Brie Larson

"He came and tackled me after I won, which made me cry," the best actress winner said after the 2016 awards show.

When Brie Larson won the Golden Globe for best actress on Sunday night, all eyes were on her — and then they quickly turned to Jacob Tremblay.

After Eddie Redmayne announced Larson's name for best actress in a motion picture drama and she began to make her way to the stage, her 9-year-old Room co-star, who was seated in the audience, adorably hopped onto his chair with excitement to give Larson a standing ovation for her first Globes nomination and win.

During her acceptance speech, Tremblay was again shown smiling in the audience as Larson said Tremblay is "half of this award, half of my performance."

Later in the press room, Larson said Tremblay brought her to tears when he greeted her after her win: "He came and tackled me after I won, which made me cry."

In the film, Larson plays a mother in captivity who was forced to raise her son (Tremblay) in a garden shed after she ends up pregnant by her kidnapper. Off-screen, the co-stars bonded on the set by eating pizza and playing with Legos.

Larson, who wore a custom Calvin Klein gown to the 73rd annual awards show, was nominated alongside Cate Blanchett (Carol), Rooney Mara (Carol), Saoirse Ronan (Brooklyn) and Redmayne's co-star Alicia Vikander (The Danish Girl).

After the show, the pair planned to celebrate Larson's win together. “I feel like we’ll probably go get something like a burger now," she said.
