-- Hollywood's biggest stars attended Sunday night's Oscars but it was a 9-year-old actor who stole the show.
"Room" star Jacob Tremblay stood on top of a box on the stage at the Dolby Theatre to present an award alongside fellow child actor, Abraham Attah.
"I'm presenting Best Live Action Short because I'm short," Tremblay joked to "Good Morning America"'s Amy Robach before the show.
"It feels pretty cool," Tremblay said of all the attention he's received this awards season.
"Jacob Tremblay, my partner through this in every way possible," Larson said.
Tremblay, who shared his Oscar experience with his fans on Instagram, had a fan-boy moment himself when C-3PO, R2-D2 and BB-8 came on stage to present an award.
