"The couple are thrilled about the new addition to their family," the rep said.

Rumors began swirling that Nicky was pregnant when she cradled her belly as photographers snapped her pic at the Valentino Haute Couture runway show during Paris Fashion Week on Wednesday. The New York native wore a bright pink cape dress by the designer for the occasion, pairing the pretty frock with studded stilettos and silver statement earrings.
