Sheryl Sandberg is back - and this time, instead of convincing us to 'lean in', she wants us to 'Ban Bossy'. Sheryl is on a mission to banish the 'b' word, which has long carried heavily sexist connotations for women at the top of the career ladder. And she's serious about it: she's even got Beyoncé "Queen B" Knowles involved.
In fact, Sheryl has called in all of her 'A-list' favours - with actresses Jennifer Garner and Jane Lynch, our very own Victoria Beckham and Condoleezza Rice, the former US Secretary of State, adding their voices to the cause. Each one has come together with LeanIn.org and Girl Scouts to promote leadership among young girls... and make existing prejudices a thing of the past.
For years, the word bossy has been used as an insulting slur on female leaders - something which Sheryl has said in an interview with Yahoo, that she's experienced since she was a child. "I was called bossy in the ninth grade," she said. "My teacher took my best friend Mindy aside and she said 'You shouldn't be friends with Sheryl. No one likes a bossy girl.' That hurt.
"We call (women) too aggressive or other B-words in the workplace. They're bossy as little girls, and then they're aggressive, political, shrill, too ambitious as women."
VB wrote that "it is thought-provoking that a man in charge may be described as commanding, however a woman in the same situation may be called bossy," on her Ban Bossy profile, and tweeted to encourage others to join her.
And Jane Lynch, who stars in Glee, said, "I would tell my 10-year-old self not to be afraid to step up and say what you think. Do not be afraid to express your opinion.
"Do not be afraid to suggest things. Do not be afraid to lead."
Heck, even the First Lady Michelle Obama herself has given her two cents. But - could you guess? - it's Beyoncé who steals the show. In the campaign ad for Ban Bossy, which has already been viewed almost 750,000 times since this morning's launch, signs off the video by saying: "I'm not bossy, I'm the boss."
Of course she is.
Now watch the video now below - and get involved with the campaign by tweeting #BanBossy.
