Although the Academy never officially announced there will be no host, it's looking like the show will be hostless for the third year in a row.
The 2019 show was the first hostless show since the 61st Academy Awards in 1989.
The 2021 Oscars will be held at the Dolby Theatre in Hollywood, Union Station in Los Angeles and international locations via satellite.
"In this unique year that has asked so much of so many, the Academy is determined to present an Oscars like none other, while prioritizing the public health and safety of all those who will participate," a spokesperson for the Academy shared in a statement in February.
During an appearance on "Good Morning America" earlier this month, Jesse Collins, a producer for the show, spoke about why it was so important to have an in-person show this year.
"A year ago, this was not possible, but it's turning," he said. "It's important that such a big show -- an event that the entire world is watching -- that we show what's possible -- with science and common sense."
A slew of notable stars are expected to present at the 2021 Oscars. The Academy previously revealed some of the talent, including Angela Bassett, Halle Berry, Bong Joon Ho, Don Cheadle, Bryan Cranston, Laura Dern, Harrison Ford, Regina King, Marlee Matlin, Rita Moreno, Joaquin Phoenix, Brad Pitt, Reese Witherspoon, Renée Zellweger and Zendaya.
Collins, Stacey Sher and Steven Soderbergh are the 2021 Oscars producers.
