If you're an A-lister in attendance, then the last task on your list is prepping for the big night.
But if, like us, you'll be tuning in from the comfort of your own sofa, it's officially time to make your predictions.
After swotting up on the films and checking who's already been triumphant at award season's previous events, we're ready to share our best educated guesses - but can you work out who'll triumph in six of the biggest categories?
See our predictions and cast your votes in these polls...
Best Supporting Actor
Who's nominated? Willem Defoe (The Florida Project), Woody Harrelson (Three Billboards), Richard Jenkins (The Shape Of Water), Christopher Plummer (All The Money In The World) and Sam Rockwell (Three Billboards)
Awards season success so far: Sam Rockwell has achieved a clean sweep, triumphing at the four big ceremonies, the Golden Globes, SAG Awards and Baftas.
Who should win? While we'd love to see Willem rewarded for his work on indie film 'The Florida Project', it seems most likely that Sam will bag the big one for his portrayal of controversial policeman, Jason Dixon.

Best Supporting Actress
Who's nominated? Mary J. Blige (Mudbound), Allison Janney (I, Tonya), Lesley Manville (Phantom Thread), Laurie Metcalfe (Lady Bird) and Octavia Spencer (The Shape Of Water).
Awards season success so far: Allison Janney has also triumphed at all of the big ceremonies, beating off some seriously good competition along the way.
Who should win? We're back Allison on this one. Here's what she had to say about the Oscars when HuffPost UK caught up with her last month.

Best Actor
Who's nominated? Timothée Chamalet (Call Me By Your Name), Daniel Day-Lewis (Phantom Thread), Daniel Kaluuya (Get Out), Gary Oldman (Darkest Hour) and Denzel Washington (Roman J Israel, Esq).
Awards season success so far: Gary Oldman has - yes, you guessed it - won this prize at the four main ceremonies.
Who should win? We're rooting for the underdogs here and keeping our fingers crossed for an upset. Can you imagine the speech Daniel Kaluuya - who won the Bafta Rising Star prize - would give? Or the smile Timothée would crack if he gets to go home with one of the golden statuettes? Is it too late to get t-shirts made? We're getting t-shirts made.
