Kim Kardashian and Chrissy Teigen have joined Fergie's racy mother's club in the video for her new single, MILF $. Reality TV star Kardashian, who gave birth to her second child in December, and new model mother Teigen join a line of celebrity guests in the summer track.

This will be Fergie's first single from her second solo album Double Duchess. The 41-year-old singer, who has son with husband Josh Duhamel, released the fascinating clip for her new track on Friday, 1 June.

Ciara, Alessandra Ambrosio, Gemma Ward, Tara Lynn, Devon Aoki, Angela Lindvall, Isabeli Fontana, Amber Valletta and Natasha Poly round out the sexy mummy squad.

The chorus is: "You got that, you got that, you got that milk money / I got that, I got that, I got that MILF money."

In the clip, the A-list celebrities are neighbours in Milfville while a "milfman" drives around delivering milk.

The former Black Eyed Peas singer claims she's switching up the X-rated definition of MILF. "Changing the acronym to Moms I'd Like To Follow is about empowering women who do it all," says Fergie in a statement.

"They have a career, a family, and still find the time to take care of themselves and feel sexy. With a wink of course :)."

At the end of last year, the 41-year-old singer revealed that she is ready to be a mother for the second time with husband Josh Duhamel, once she's done with her new solo album and tour. Fergie told E! News that: "After the album and the tour, we would love to have another child. Absolutely."

The American singer, who already has a two-year-old son Axl with Duhamel, strongly hinted that she would like to have a baby girl next time.

The video shows the ladies pampering themselves at the 'Milf Spa', where Fergie dances with her backup dancers.

When she was dating her now 42-year-old husband, they discussed how many children they wanted as early as the second or third date.

The star recalled the conversation, telling E! news: "We negotiated early on to have two kids, because he said he wanted five."

She continued: "And I was on the date going, 'OK, well, we could be really good friends, but my limit is two.' That was date two or three. That was it. Why waste time?"
