THERE was a kerfuffle at Coachella when a member of rapper Tyga’s entourage lost his iPhone in a lake. “Tyga caused a scene, prompting a search by nearly everyone on the property,” said a spy at the Gravity SUV mansion Sunday during 1Oak’s party where guests included Leo DiCaprio and Timothée Chalamet. “Sushi by Bou’s chef David Bouhadana dove into the water with goggles. They put [the soggy cell] in rice.” Tyga (above) was with Iggy Azalea, and they were looking cozy throughout the weekend, canoodling at a Tao x Revolve bash and leaving just before Tyga’s ex, new mom Kylie Jenner turned up with Travis Scott. Kendall Jenner managed to avoid on-off beau, Blake Griffin at Bootsy Bellows’ bash by McDonald’s and PacSun.
