The actress revealed that she and her husband Will Kopelman are now proud parents to a newborn daughter.
A spokesperson for the star told Life&Style: ‘We are proud to announce the birth of our daughter, Olive Barrymore Kopelman, born September 26th, healthy, happy and welcomed by the whole family.’
The statement then went on to say: ‘Thank you for respecting our privacy during this most special time in our lives.
Her efforts to keep the baby secret are in stark contrast to Drew’s own childhood, as she kick-started her career in a commercial at 11-months-old.
The 37-year-old seems to finally have found domestic bliss with her third husband Will, an art consultant and the son of former Chanel CEO Arie Kopelman.
Drew and Will began dating in early 2011 and married in June, with the Never Been Kissed star walking down the aisle heavily pregnant and wearing a custom Chanel gown, designed by Karl Lagerfeld.
The name Olive may strike fans as unusual, however it is becoming increasingly popular among celebrities, with Sacha Baron Cohen and Isla Fisher naming their daughter this, as well as former Doctor Who actor David Tennant and his wife Georgia Moffett.
