Jennifer Aniston photobombed J.Lo, John Travolta kissed (a slightly reluctant) Scarlett Johansson and Lady Gaga hit the tiles - literally.
Oscars red carpet non-withstanding, some of our favourite moments from this year's show came from the candid and hilarious backstage photos uploaded by obliging celebrities, stylists and other insiders on Instagram.
These snaps cast a whole new light on the biggest night of the Hollywood calendar, revealing a level of detail and colour we had no idea of previously.
Who knew that Naomi Watts likes to prep for the red carpet with a pre-awards frittata. Or that Meryl Streep is so game for a laugh, sharing mid-ceremony "foot-bumps" with Jennifer Hudson and posing for selfies with J.Lo?
Love was certainly in the air last night, as Elton John cosied up with Kylie Minogue and Jared Leto, Gaga embraced Julie Andrews and Reese Witherspoon shared her mum's adorable good-luck texts.
From pre-party pampering (some did yoga, others channelled Prince) to the sheer drama of the ceremony backstage, and the after-party jaunts, come see our favourite behind-the-scenes Instagram snaps from the 2015 Oscars.
