Gottsagen received a standing ovation after delivering the familiar line "And the Oscar goes to ..."
LaBeouf, however, received some criticism for the presentation, accused of laughing at Gottsagen.
"Honey Boy" director Alma Har'el took to Twitter to defend the 33-year-old actor.
"Shia was offered to present an Oscar," she tweeted. "He said he would do it if he can share that moment with his beloved co-star Zach Gottsagen who we all adore. It's stressful up there..."

Before the film's release, LaBeouf spoke highly of his "The Peanut Butter Falcon" costar.
"He's very loving, not very judgmental of critical. There's no irony in him," said LaBeouf. "So those kind of aspects, like character, yeah, character, integrity, stuff like that. Very honest person. He's never lied in his life. He doesn't curse. He's quite pure."
