Beyoncé or Sam Smith?

Ariana Grande? What are you doing here?

She shared the news with a "Labor" Day tweet.

In the music video for "Somethin' Bad."

Husbands: just around to brighten your outfit. 

Jason Derulo? Is that you?

Amber Rose channeled V. Stiviano.

Beyoncé, sadly, was nowhere to be found. 

Gwyneth Paltrow! Lupita Nyong'o! Tracy Morgan?

Wide eyes, loose lips.

Carrie Underwood was the first famous face to show up.

"Mean people need Jesus."

Laura Benanti's pantsuit, Carrie Underwood's acting, and those swastikas.

Oh boy.

"I do hope it works for Carrie, because she's lovely and I'm a fan."

It's pretty charming.

The battle of the poufs.

Taylor, Carrie, Kacey ... and Diddy.
