— -- It's Hollywood's biggest night and hours before the Academy Awards, the stars are getting ready in different ways.
"Got up early to get some good, quiet Sunday work done in my office and this little tiger wakes up, wanders in and wants to watch 'Mo'.. short for Moana," he wrote in a caption. "And aaaaall daddy's work comes to a screeching halt."
"We're excited for tonight's #Oscars. Grateful to be nominated! Time to hit the gym and yes, standing up while I work at my desk is my jam," he added.
Johnson starred in the Disney animated film "Moana," which earned two Oscar nominations -- one for best animated feature film and one for best original song for "Hamilton" creator Lin-Manuel Miranda's "How Far I'll Go."
In fact, Miranda will perform that song with "Moana's" Auli'i Cravalho. She shared a sneak peek of her look hours before the show.
Oscar-nominated singer Justin Timberlake, who is set to perform his hit "Can't Stop the Feeling!" from the film "Trolls," also shared on the social media network that he was warming up hours before the show, which will air live at 8:30 p.m. ET from the Dolby Theatre.
Meanwhile, other stars chose to spend the hours before the 89th Academy Awards, hosted by Jimmy Kimmel, relaxing.
Octavia Spencer, who is nominated for best supporting actress for her role in "Hidden Figures," relaxed with a bath and her favorite coffee.
Naomie Harris, who is battling her in the same category for her role in "Moonlight," got a facial.
She described it as a "a moment to relax and reflect before the glamour and mayhem begins," she wrote in a caption.
Composer Dustin O'Halloran, who is nominated for best original music score for his work on "Lion," decided to be one with nature before the big show begins.
And it looks like presenter Rix Ahmed, who stars in HBO's "The Night Of," already got his hands on a coveted tropy...a faux one.
Meanwhile, Janelle Monae, who starred in two Oscar-nominated films, "Moonlight" and "Hidden Figures," reflected on this milestone moment.
"This is a really...special day," she said in a video. "Some of you may not know it...but as a little girl I've always dreamt of going to the Oscars and I get to go today. I get to be in the room of true artists, people who have inspired me along the years."
Ava Duvernay, whose documentary "13th" is nominated for Best Documentary Feature, shared the day with her family and glam squad.
"A lovely evening has begun. Fam in one pic. Glam in the other. Warm energy. Much love. In dark times, we are a light for each other," she wrote as a caption on Twitter.
