Social Scene: Week of Feb. 27

Hollywood's biggest night resulted in some amazing celebrity Instagram activity!

Some of the world's hottest stars snagged tickets to Vanity Fairs Oscars party on Sunday night, and Jessica Alba, Reese Witherspoon, Katy Perry and Kate Bosworth were just some of the stars that appeared in some of the behind-the-scenes action on Instagram the next day. Taraji P. Henson also shared a hilarious side-eye photo from the red carpet.

Not all of our favorite Instagram moments this week were from the Oscars, though. The next morning Octavia Spencer hung out with Tim McGraw at "Good Morning America," Kim Kardashian shared a gallery of selfies with her son, Saint, and Nicki Minaj teased a major upcoming music video with a BDSM-inspired red leather ensemble.

Mariah Carey also turned a lot of heads with her PDA-filled selfie with boyfriend Bryan Tanaka.
