Serena Party Watch: Serena "ReRe" Williams picked up her partying ways this weekend. The former World No. 1, who was a staple at New York fashion week, attended HBO's Emmy Awards party last night. ReRe opted for a lavender halter top dress, black clutch, black Christian Louboutin peep-toe stiletto heels, and unfortunate hair extensions. We were really loving the messy bob she was sporting recently, but clearly she's over it.
