‘Heated Rivalry’ creator Jacob Tierney shares behind-the-scenes secrets about season 1 — and what's to come in season 2! Fans of the book series know Rihanna’s ‘Diamonds’ plays during a pivotal wedding scene, and ET’s Emily Curl asks Jacob if the song will make it into the show. Jacob jokes, ‘This show has not changed budget. I don’t think we can afford all those diamonds.’ ‘Heated Rivalry’ season 1 is streaming now on HBO Max, while Jacob's book about bringing the story to screen, 'll Believe in Anything: The Making of Heated Rivalry Season 1,' is out Oct. 13.
