The acronym of the song, which Fergie tells Entertainment Weekly in a statement is "about empowering women who do it all," stands for "Moms I'd Like to Follow."
"They have a career, a family, and still find the time to take care of themselves and feel sexy," Fergie told EW. "With a wink of course."
At the end of the clip, from "Anaconda" director Colin Tilley, there was even a screengrab of an official "MILF Money" Instagram account – which already has nearly 10K followers. It includes short video loops of all of the video's stars, and a few must-see selfies.
Kardashian West, Fergie and Teigen team up for one shot, while another shows the former Black Eyed Peas front woman with Ciara.
Ciara also posted a full body shot of her video outfit to Instagram.
The video also shows Fergie and Kardashian West pouring milk over their bodies.
Alessandra Ambrosio, Devon Aoki, Isabeli Fontana, Tara Lynn, Angela Lindvall, Natasha Poly, Amber Valletta and Australian model Gemma Ward also feature in the clip.
"M.I.L.F.$." is the first song released from Fergie's upcoming album, expected to be titled Double Dutchess. In June, she also released a teaser of what is potentially another new track called "Hungry."
Fergie has a 2-year-old son, Axl, with husband Josh Duhamel.
