Parties! The style, stars and scoop from Hollywood's hottest events

Rihanna was positively glowing—thanks in part to her neon ensemble—when she opened for Kanye West on his Glow in the Dark Tour at the HP Pavilion in San Jose, California. The singer's first big nail moment? "I was 4, and my great-grandma was watching us. I went into my mom's room, took her nail polishes, opened them, and painted "bracelets" up my arm," Rihanna told In Style in February. "When my mom came home, she got really upset. I got scared because I thought, 'My gosh, I have to go to school like this!' Because we never used to have nail polish remover."
