The cast just revealed a MAJOR SPOILER for S2 of 'Stranger Things'

GUYS. WHAT THE ACTUAL FFFFFFFFFFFFFFFF.

The 'Stranger Things' cast are currently at the Emmys, and while they were being interviewed on the red carpet one of them dropped a MASSIVE SPOILER about the highly anticipated second season!

Gaten Matarazzo, Caleb McLaughlin and Millie Bobby Brown attended their first Emmys event this afternoon, and absolutely SLAYED the red carpet (see the totes adorbs pics above). 

Millie, who plays the character or Eleven, basically told us that she will NOT BE COMING BACK FOR SEASON 2.

Speaking with E!Online, she said, "I don't know know if I'm going to be back." 

"It's very exciting if I am back, and if not, it's been a great season."

SHE HAS TO BE IN SEASON 2. WHAT IS GOING ONNNNNNNNNNNNNNNNNNN??? THIS IS NOT OKAY.

On another (more upbeat) note, these cute kids performed "Uptown Funk" at the Emmy's opening ceremony:
