"Will is just thrilled — we both are," said Drew. "We just wanted so badly for Olive to have a sibling. In some ways, it's really for her. So congratulations, Olive!"
The doting mother gave birth to her first child in September 2012. "She's a sweet person, which is all I care about," said Drew. "I am obsessed with nice. That's the most important thing."
The 38-year-old actress recalled the joyous moment when she found out she was pregnant again.
"I was overjoyed," said Drew. "It always feels so surreal, it's incredible. [I'm feeling] incredible, that, 'Here we go again' feeling. And blessed. Blessed."
Speculation that the mother-of-one was pregnant started when Drew was spotted wearing loose clothing. The blossoming actress seemed to be hiding a baby bump beneath a floor-length gown when she attended the LACMA Art+Film gala event at the weekend.
