The stars poured into CAA’s pre-Oscars party at Living Room in Los Angeles Friday night … including “Heated Rivalry” stars Connor Storrie and Hudson Williams, who smiled wide at the camera while posing cheek-to-cheek.

MIA was their costar, François Arnaud … who, as you know, is rumored to be dating Connor.

We saw Connor and François last month, getting close and enjoying dinner at the Smoke House in Burbank, CA, but still … no confirmation that they’re the real thing.

Other than the ‘Rivalry’ stars, Jon Hamm made the pre-Oscars shindig a date night with wife Anna Osceola, while Rita Wilson went solo … with no Tom Hanks in sight.

The stars were all smiles as they mingled with their peers — you can see newly-single Sacha Baron Cohen posing with his “Borat Subsequent Moviefilm” collaborator Maria Bakalova, Anya Taylor-Joy, Tracy Brennan and more … just check out the gall.

The 98th Academy Awards will air live Sunday night with Conan O’Brien hosting the second year in a row.

There are plenty of potential history-making wins — “Sinners” could break the record for most wins by any single movie in Academy Awards history, Autumn Durald Arkapaw could become the first woman to win for cinematography for “Sinners” … the list goes on.
