Katy Perry and Julianne Hough Party Poolside on Day One of Coachella

Katy Perry, Julianne Hough, Sophia Bush, and Eli Roth were among the stars who attended this afternoon's Shop Bazaar party at The Parker in Palm Springs. We stopped by the Coachella weekend bash, which was hosted by Harper's Bazaar and drew dozens of stylish guests. The event even featured a pop-up boutique where guests could shop for swimsuits, jewelry, and beach towels to complete their festival looks. As the afternoon went on, DJ Mia Moretti took a break from the turntables to take photos with her friend Katy Perry, who is a fixture at Coachella each year. A recently single Julianne Hough also hung out by the pool and shared a few laughs with a group of female friends. After the party, we spotted Sophia at the field, where she checked out the bands Passion Pit and Tanlines.
