The 32-year-old actress and her producer husband Adam Shulman are having a baby, reports eonline.com.
“Anne is in her second trimester and feeling great,” a source said.
“The Devil Wears Prada” star was spotted in Beverly Hills earlier this week with what appeared to be a baby bump.
The couple married in 2012 and Hathaway had previously spoken of her desire to start a family.
The actress earlier shared that she and Shulman had been trying to decide where to live once they have children as she wants to keep them out of the spotlight.
