The star is also ready to reveal the name of their soon-to-be second child. Liberty Grace has a bit of family history to it. The first name "is something I've always loved," Lawrence, 33, explains, while Grace is in honor of his grandmother, who passed away earlier this year.
Lawrence jokes about his house full of girls.
