Blake Lively passionately shut down a reporter who asked her about fashion at a Power of Women event in New York on Friday.

The actress was attending the event where she was being honoured for her work with Child Rescue Coalition, a non-profit organisation which aims to track online predators who target children.

On the red carpet for the event, Lively was asked by one of the reporters "What's your power outfit?"

"Come on, you want to talk about an outfit here, today?" she responded. "No way. Come on. Come on, we’re about building women up. Come on, outfits? Would you ask a man that?"

After the reporter offered clarification, The Shallows star countered: "But you wouldn’t ask a man what his power outfit is, I’m sorry. Like see, this is the moment that we become more aware and that we change."

She concluded with: "So you can ask me another question". 

The 29-year-old actress, who has two daughters with husband Ryan Reynolds, accepted her award at the event with an emotional speech.

"I’m here today because I’m a mama, and I have two baby girls - they’re not babies, but I think they are -James and Inez, and they are my world, and I would do anything to protect them", she said.

"I would literally die for them, without a moment’s thought, and for those of you who have children, I think you know what I’m talking about."

"The sexual exploitation of children is something that isn’t happening rarely, it’s not happening worlds away, it’s happening right here, and right now", she added.
