A gaggle of strong, self-made women, including Alicia Keys, Serena Williams and Estelle, came out to Gucci's Fifth Avenue flagship last night to celebrate Mary J. Blige and her Foundation For the Advancement of Women Now (aka FFAWN).

All day long, 10 percent of the shop's sales were donated to the foundation, while Gucci's creative director, Frida Giannini, launched her specially designed Twirl for FFAWN watch (it's available today in US and Canadian Gucci locations and select department stores).

The city of New York also showed its support for the cause. Once the sun went down, Blige lit the iconic Empire State Building in FFAWN's signature hues of purple, yellow and gold.

"We're representing the colors of the phoenix, a mythical bird that regenerates itself through beautiful things," said Blige. "Like [strong women], they can't be held down, ever."

Next week, Blige will be cutting the ribbon on FFAWN's first center for women in her native Yonkers. "Women are in there being helped. And these women come from places that I've come from -- hard times and hardship," said Blige. "They want to get educated, inspired and encouraged."

Also getting inspired, sartorially speaking, was Williams, in an of-the-moment asymmetrical Gucci minidress.

"What's there not to love about Gucci?" said the tennis star. "They make great shoes and great bags. I'm so inspired. Just seeing their designs makes me want to work harder on my designs."

As for any commentary on Williams' meltdown at the U.S. Open, she was staying mum (staying huddled in the corner with Lebron James). But Donald Trump wasn't.

"She did nothing wrong!" he shouted at whoever would listen. While Williams replied, coyly: "He obviously knows what he's talking about."

Oh, snap!

Not sure what all the fuss is about? Here's the scoop.
