If there’s one thing in life women of any age should never do, it’s break the “Girl Code.”

And to spread that awareness, Real Housewives of New York City‘s Countess LuAnn de Lesseps debuted a new girl-power hit called “Girl Code (Don’t Be So Uncool)” on iTunes.

The Countess tells PEOPLE the song was inspired by the women on the show: “This is about girls who steal boys from other girls,” says de Lesseps, 50. “It’s an anthem for all women everywhere to have each other’s backs. It’s really multigenerational from a young age to women who are much older.”

To educate women beyond the lyrics of her third single, de Lesseps shares seven rules a woman should never break:

Don’t Steal Her Man

“If you want to keep your girlfriends, always know when it’s appropriate to flirt.”

Be a Good Wingwoman

“It means you share the bill – and always have each other’s back.”

Be Supportive

“Never bash a girl’s career. And always be honest when a friend asks, ‘How does this look?’ ”

Keep Secrets

“Don’t gossip about each other and never speak of nips and tucks.”

Always Share Designer Everything

“This is so prevalent in the television business: If you or a friend has an ‘in’ with a designer, you should always share that.”

Don’t Drink and Text Each Other


Be Inclusive of Other Women

“Don’t be a friend stealer! It drives me crazy when a girlfriend steals another girlfriend.”

Never Let Her Get Bangs

“They take forever to grow out.”
