Gold Derby is serving up Big Brother 28 spoilers all summer long. Speaking of which, the Week 5 Veto competition took place in the backyard on Saturday, and the winner was ...Kamu Kirk! This is the MMA fighter's second big win after claiming the HOH key in the third week, which led to Jason De Puy's eviction. Late last night, Chuk and Haley were blowing off steam about Kamu, feeling like they’re the only two still trying to keep their alliance together. Chuk wants to keep working his cowboy magic on Kamu, but he's running out of time, as the Veto ceremony will take place Monday afternoon.
