The Hollywood star currently has a lead role in the American fairytale drama series, Once Upon A Time and has also appeared in films such as Something Borrowed and Mona Lisa Smile.
But now she is preparing for one of the biggest roles of her life: being a mum!
Ginnifer's rep confirmed the happy news to People.
This year has proved to be full of reasons to celebrate for the 35-year-old, as her Once Upon A Time co-star Josh proposed in October.
The couple appear to have created their own real life fairytale, after falling for one another on the television set.
They began dating in 2011, but waited until the following year before going public with their relationship.
Congratulations Ginnifer and Josh!
