Fergie has always been a "hardcore" Taco Bell fan and "goes hard" when she dines there.
The 'M.I.L.F.$' hitmaker has confessed she likes to indulge in a "binge meal" from the Tex-Mex fast food giant now and again, and when she indulges in the tasty treat her meal turns into absolute carnage because she orders everything spicy on the menu.
Speaking to NME magazine about her favourite feats, Fergie said: "I absolutely do. It's a binge meal for me, so I don't do it all the time. But when I do, I go hard."
The 41-year-old singer explained that she's a big fan of spicy food, so heads for the hot sauces, and that she's a seriously hardcore fast food fan.
Fergie said: "When I'm in a Taco Bell, all I'm thinking about is how many hot sauces I can grab.
"In that situation I'm, like primal. That's how serious I am about fast food."
The singer songwriter eternally pledged her loyalty to the Tex-Mex chain by immortalising her passion in a lyric to her smash hit single 'Glamorous' in 2006.
She sang: "I still go to Taco Bell/Drive through, raw as hell."
Meanwhile, the mother of one - who has two-year-old son Axl with her husband Josh Duhamel - has revealed her spouse was the inspiration behind her recent track because he used to joke about her nursing their son.
Speaking about the muse for her latest record, the blonde beauty said: "When I was breastfeeding, my husband would come in and say, 'The Milkman is here!' - which helped with the lyrics because all these different milk puns would come into my head."
And Kim Kardashian West, who stars in the raunchy music video to Fergie's new single alongside Alessandra Ambrosio and Chrissy Teigen, was "totally" keen to star in the clip.
Speaking about the 'Keeping up With the Kardashians' cameo in the video, Fergie said: "She totally got it and was super cool."
