This is too late to be a Mother's Day gift, but your mom will appreciate it nonetheless!

Fergie -- or as the government calls her, Fergie Ferg -- dropped her new single, "M.I.L.F. $," on Friday. It's not the first taste we've gotten of her forthcoming album, Double Dutchess, but with the 41-year-old pop star screaming, "Now let me see your MILF shake!," it's certainly the most memorable.

Take a listen below. (Pro tip: It helps if you imagine hearing this at 1:30 a.m. on the dance floor when you are a cocktail or six deep.)

"You got that, you got that, you got that milk money / I got that, I got that, I got that MILF money," Fergie sing-raps over a bouncing beat, which is either a brag about getting paid or a reference to the most inappropriate episode of Leave It to Beaver ever.

Oh, and the tres subtle single cover features only a wink at Ferg's signature humps:

Just kidding! It's humps for days! The "London Bridges" singer shared a couple other cleavage-heavy pics from the shoot, including one where she is pouring milk on herself and promises the "M.I.L.F. $" video is coming "sooner than you think..."

On the topic of her MILF-ness, husband Josh Duhamel recently joked that the couple's 2-year-old son, Axl, looks so much like Fergie that, as he says, "I'm not even sure if this is my son!" Watch in the video below.
