Hollywood's hottest stars were ready to let loose at the soiree, which was held at the Wallis Annenberg Center for the Performing Arts in Los Angeles following the ceremony.
Seliger captured a collection of classic photos of some of the night's brightest stars, including Sofia Vergara, Oprah, Lady Gaga, Rita Ora and many more.
Kate Upton was snapped photobombing Leslie Mann and Judd Apatow's love-filled pose as Jennifer Aniston and Justin Theroux proved they're the cutest couple in Tinseltown.
