She stopped by Milk Boutique to support pal Masha Gordon at her If Pockets Talked pop-up shop, where Samantha Ronson DJed. The evening out was just the latest in a string of events for Nicole, who also attended Mindy Kaling's book launch party at the Roosevelt Hotel on Monday. Over the weekend, Nicole hosted a Winter Wonderland event with Baby2Baby and also dressed up for the MOCA Gala. She was just one of many famous faces at the glamorous museum night, including Gwen Stefani and Rachel Zoe.
