The American singer released debut solo album The Dutchess in 2006, boasting hits like London Bridge, Glamorous and Big Girls Don't Cry. Since then she's performed with her band Black Eyed Peas as well as offering tracks to the Sex and the City and Great Gatsby soundtracks, and even released track L.A. Love (La La) as a potential comeback single in 2014.

But now she's made her official comeback, dropping M.I.L.F. $ online on Friday morning (01Jul16), along with a sexy hint at what fans can expect from the music video to accompany. In a moving photo on her Twitter page Fergie, 41, is seen wearing a cropped yellow top with high-waisted navy bottoms, seductively pouring a bottle of milk down her front in slow motion.

"#MILFMONEY on @AppleMusic. Just getting started, video coming sooner than you think..." she captioned the gif.

Purring out lyrics like, "You got that, you got that, you got that milk money / I got that, I got that, I got that MILF money," the track is already generating buzz amongst fans, with one admitting she's had it on repeat since she woke up.

It's what Fergie's followers have been waiting for since she announced her second album, Double Dutchess, last summer (15), promising fans a 2016 release. She also shared a clip from a track called Hungry on Instagram just a few weeks ago.

As well as playing shows and lending songs to movies since her first record, Fergie married actor Josh Duhamel, 43, in 2009 and gave birth to their son Axl in August 2013.
