Beyonce's song 'Grown Woman,' which first appeared in her Pepsi ad, has leaked online. Produced by Timbaland and co-written by The-Dream, it's a headstrong women's anthem.

Less domineering than her previous anthem, 'Run the World (Girls),' it still has the sass and fierceness that we expect from Beyonce.

On the song, Queen Bey celebrates her womanhood and doesn't care if haters are going to hate.

"I can be bad if I want / I can do wrong if I want / I can live fast if I want / I can go slow all night long / I'm a grown woman, I can do whatever I want," she sings on the bridge.

On her second verse, Beyonce reveals that she's self-empowered and is ready to show the world what kind of woman she has become.

"They like the way I walk, because I walk with a vengeance / They listen when I talk, because I ain’t pretending / Took a while, now I understand, Just what I’m going to do / Now I know who I am, 'bout time I show it," she sings.

No word if this will be the lead single from Beyonce's upcoming album, but it should be.

Beyonce is ready to take over the R&B game. Bow...down...bitches.
