In her latest GOOP newsletter, our favorite wannabe-Brit Gwyneth Paltrow admits to having a "frenemy." How Mean Girls of you, Gwyn!

Apparently, this person from her past was "hell-bent on taking me down," declares Paltrow. "I was deeply upset, I was angry, I was all of those things you feel when you find out that someone you thought you liked was venomous and dangerous."

So what happened? "One day I heard that something unfortunate and humiliating had happened to this person. And my reaction was deep relief and... happiness."

OMGOOP, Gwyn! Actually, this is kind of hilarious for her to reveal. We've all been there!

But who could she be talking about? I hope not Madonna!
