I wanted the freedom to go out and live my life.”

She added that she was making the most of spending one-on-one time with her musician husband. “In the beginning [of pregnancy]it was very emotional for me,” she told W. “Like, 'I love this man so much. How can I bring someone else into this?' I try to enjoy these days when it's Justin and I, just the two of us.”
