The event, held at Ida and Harry at Fontainebleau, was a meet and greet for Nicole and fans, allowing them to check out her designs! She also promoted the line with an appearance on Regis and Kelly.

Nicole, 27, and Joel, 30, expect their second child late this summer. The new baby will join big sister Harlow Winter Kate, 16 months.
