Fergie insists there's "nothing wrong" with mums being a little naughty sometimes.
The 41-year-old singer is hoping to find success with her comeback single M.I.L.F. $, which includes saucy lyrics such as: "Heard you in the mood for a little MILFshake, Welcome to the Dairy Dutchess Love Factory, I could whip it up, fix you up straight away
Come on in the front door, leaving at the back door."
And Fergie said in a new interview with Billboard.com that she is hoping the song will "empower" mothers to have some fun and embrace their inner sex kitten.
"This is definitely empowering moms to have fun," she said. "Being a mom and having a career, taking care of yourself and still being able to be flirty and fun and a little naughty sometimes - there's nothing wrong with that.
"Society tries to tell moms what they should and shouldn't be, and it's just a little freeing to have fun with pushing those limits a bit. I might do it a little bit more than others, but that's just who I am."
The video for the song shows Fergie alongside a host of stunning beauties, such as Kim Kardashian, Chrissy Teigen and Alessandra Ambrosio. Several scenes show the video stars drenched in milk, but Fergie laughed that it was "all done with a laugh and a wink... I've always poked a little fun at being sexy."
The group shot so much footage for the video that Fergie added an extended version of it could be released in the near future.
"There's so much more content that we shot ... that we're just going to keep probably presenting it to everyone," she smiled. "I think M.I.L.F. will probably have its own babies."
One person who is a huge fan of Fergie's new offering is her two-year-old son Axl. The tot, whose father is Fergie's actor husband Josh Duhamel, can't resist having a boogie when the song comes on.
"He loves it," she said. "Whenever we put on music with a really good beat, he starts dancing and he does this little bounce and we call him 'the dancing guy.'"
