Republic superstar Ariana Grande prepares for the Halloween-themed iHeart launch event for new single “Focus,” which featured a six-song set and Q&A. SBP’s Mike Chester won the Best Costume prize for his “promo weasel” getup. Later, KIIS-FM’s Beata said the secret word and a duck came down and upped the song’s spins. Seen before trick-or-treating on Pittman’s jet are (l-r) Republic’s Talia Gilboa, Beata, Grande, iHeart L.A. SVP Operations Kevin LeGrett and Chester.
