Hear Beyonce's new song 'Grown Woman'

Beyonce has gotten pretty good at keeping her still-untitled album project from springing any leaks. Today, however, “Grown Woman,” the song from her Pepsi commercial that debuted last month, has emerged in full, though, as usual, there aren’t many details available.

No confirmation on whether the song will be on the new album or if it’s her new single. It’s a catchy track, reportedly produced by Timbaland, filled with the clattering percussion that has become his trademark. And it features lyrics about female empowerment that have marked other lead-off singles, including “Run the World (Girls).” “I’m a grown woman,” she sings. “I do whatever I want.”

But maybe that’s why she hasn’t decided on it as her single yet. It’s not surprising enough for her.
