Brooke Blurton drops explosive secret about Nick Cummins on Bachelor In Paradise

SO obviously the 24-year-old doesn't reveal the secret in the teaser, but it is huge!

Sitting in the island hut with Cass Wood, Cat Henesy, and Alisha Aitken-Radburn, Brooke tells them, "I've protected him for this long."

"I don't really wanna have to protect Nick."

Again, please look at Cass' face.

WE ARE SHOCKED.

If it couldn't get juicier, Cass tells the camera: "I was not expecting that at all."

"I was actually completely shocked."

And then Brooke cooks it completely adding:

"He told me not to tell anyone... He's gonna hate me for this."

Everyone in Australia right now...
