Facebook COO Sheryl Sandberg was on “The Kelly File” tonight to announce a new initiative called “Lean In Together.”

The initiative urges men to show the world that they’re for gender equality. It also asks women to celebrate the men in their life who “lean in.”

“We’re never gonna get to equality unless men lean in as well, and they should do it not because it’s the right thing to do – even though it is – but because it’s good for them,” Sandberg said.

Sandberg cited an IMF report which said that if women entered the workforce at the same level as men, our GDP would grow by 5 percent. She said that men who work better with women will outperform their peers. On the home front, couples who share responsibilities 50/50 are happier, divorce less, and have more sex, she said.

“’Choreplay’ is real,” she said. “Don’t buy flowers, do laundry."

The Facebook COO also told Megyn Kelly about a new study, which found that girls have broader career aspirations by the age of 14 if their fathers do household chores.

In a Facebook/Insider exclusive, Sandberg spoke more about double standards in the workplace.

“Women walk a fine line between competence and being liked in a way men don’t do,” Sandberg said. “When men are more competent, they’re better liked. With women, when you seem competent, people like you less because you can’t be nice if you’re competent, and when you seem nice, people think you’re not competent.”
