The blond stunner, who stars in the forthcoming "The Age of Adaline," discussed her latest endeavors in the May issue of Allure --- admitting that breast-feeding her new daughter James has become "a full-time job."
"I'm, like, driving down the road, pumping," she said.
Lively and husband Ryan Reynolds welcomed the baby in December and held off on releasing details.

"I would not be proud to be the person who gave someone the cocaine that made them overdose and then shot someone and slept with someone else's boyfriend."
After the popular CW series wrapped its sixth season in 2012, Lively went on hiatus from acting and launched her lifestyle website, Preserve, so she could "reset" her life and take "control" of her future as well as that of her "babies."
Preserve is also where Lively announced in October 2014 that she was pregnant, after concealing her baby bump in baggy clothes for seven months. She crashed the fledgling site in the process.
"That was my way of owning that moment," Lively said, explaining that she "can't" announce her news in the vein of someone like Beyonce, who flashed her baby bump onstage at the
"But it was important for us. It was a struggle, because we want to keep our privacy, but we also don't want our lives to be exploited by other people. So we did it simply; it was a quiet way, an elegant way."
