Katy Perry Leads the Star Parade at MOCA

Katy Perry made a stunning entrance at the Museum of Contemporary Art, Los Angeles, gala in LA on Saturday, flashing a smile about a month after her split from John Mayer. The singer wore a black floor-length dress to the MOCA event, where she joined Pharrell Williams, Rachel Zoe, and more stars to celebrate the museum's 35th anniversary. Both Pharrell and Rachel turned the gala into a date. Rachel was all smiles when she arrived with her husband, Rodger Berman, and Pharrell beamed as he held hands with his wife, Helen Lasichanh. Meanwhile, Jane Fonda and Dianna Agron stepped out for solo appearances. Scroll through to see the stars on the red carpet!
