It all started when the iconic actress delivered a speech before presenting the trophy for Best Motion Picture -- Drama category -- near the end of last night's show.

Close told the audience about a letter she received from the late Katharine Hepburn about the tough-as-nails business of Hollywood. (Hepburn died of natural causes in 2003 at age 96.)

Close quoted Hepburn as saying in the letter that being an actor was a "terrible profession, this terrifying profession, and, let's face it, this delicious way to spend your life."

Then Close went off the rails, proudly declaring, "We are all so f---ing blessed and lucky." Many TV viewers heard a dip in the live feed's audio to censor the foul language. But video of Close's uncensored speech was later uploaded to YouTube.

Despite this, Close presented the Best Motion Picture -- Drama -- award to Director Brady Corbet and the cast of "The Brutalist."
