E! News learned the star was expecting another little one with husband James Rothschild back in July, her rep telling us at the time, "The couple are thrilled about the new addition to their family."
While the expectant mama never revealed the baby's sex, her pregnancy seemed to be smooth sailing. "I'm feeling great! Not one day of morning sickness," she told E! News in September. "Feeling good."
As for Lily's new role as a big sister, "She is [ready]" Nicky assured us. "I don't think she knows yet, but she is."
Congratulations to Nicky, James and big sister Lily!
