Blake Lively has revealed that breast-feeding is a full-time job.

The former Gossip Girl star welcomed baby daughter James last December, with husband Ryan Reynolds, and joked that she is nursing her child all the time.

“Breast-feeding has been a full-time job,” she told Allure. “I’m, like, driving down the road, pumping.”

Blake, who graces the front cover of the magazine’s May issue in a shoot taken by Mario Testino, said becoming a mother has become her top priority.

“I feel like I’ve figured out the most important thing to me, and everything supports that.”

The 27-year-old actress also hinted that she is looking forward to having more children, particularly since she created her lifestyle website, Preserve.

“It taps into so many of my own passions, but it also is a business that I can control. If I can be successful at this, I have security for my family and my babies,” she said.

“I’m in a profession, acting, where it’s really for-hire – I offer a service that people hire out. I love it, but it’s not something I can control.”
