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

Mischa Barton and other Hollywood hipsters gathered to celebrate the opening of celebrity stylist Byron Williams’ Beverly Hills salon. The fete—hosted by close friend and self-confessed Byron devotee, Rachel Zoe—brought out Lindsay Lohan, Sanaa Lathan and Monet Mazur, all of whom sang the praises of the hair and makeup guru. “I love Byron He’s just so gentle and sweet," said Barton. "When he does makeup he pays attention to every little detail.” As he does when he throws a star-studded get together.
