The last time we saw Brooke Shields, she delivered an emotional eulogy to her longtime friend Michael Jackson at his public memorial in Los Angeles. Now, Brooke has a fun new cause to share, and hint hint: It involves parties!

"We're sort of bringing back the Tupperware party," Brooke tells ET's own Mark Steines. "There's this sort of kitsch aspect to it. It's fun. I think people started making fun of it, but I guarantee you people are rushing to the table to see the product."

But Brooke isn't just pitching a new product; she's involved in Tupperware Brand's Chain of Confidence campaign, which is giving a million dollars to the Boys & Girls Clubs of America to support the SMART Girls program, among other worthy building block causes.

"There's this constant way of thinking of paying it forward," she says. "It's a campaign that celebrates women, that empowers women, that celebrates the relationships women have and the independence that they derive from those relationships."
