Kunis wowed in a fabulous figure-hugging dress by Lanvin while Timberlake dressed to impress in a grey suit. (We know they aren't going out but they do make a nice couple, don't you think?)
However, Mila wasn't the only one to make a statement in red. Emma Stone's unique sense of style paid off last night; she looked stunning in a Giambattista Valli sweater and skirt ensemble teamed with a pair of nude Louboutins.
Olivia Palermo also showed off her on-trend look in a floral maxi skirt and metallic lace-up heels. She looked effortlessly chic (as always) but Stone definitely got our vote for best dressed. How do you rate the stars' red carpet styles? Let us know in a comment below.
