On Sunday, stars geared up for the spectacle in LA by showing off their hot looks. Jennifer Lopez flaunted her cleavage, Scarlett Johansson was pretty in neon pink, and Miles Teller looked picture-perfect with his girlfriend, Keleigh Sperry. As for most adorable duo, Judd Apatow couldn't have been cuter with daughter Iris.

With Amy Schumer bringing her brand of humor as host and several movie stars nominated in fun categories, this year's show was one you didn't want to miss. Read on to see celebrities start the party, and then get nostalgic with a look at the show's most '90s-tastic moments and the hosts you probably forgot about.
