The Black Eyed Peas frontwoman took to the talk show to promote her new line of low calorie vodka, Voli, while also being reminded by Fallon about an awkward moment from years ago in which he and she shared a smooch.
As for Fergie's new booze offerings, she was asked what it is that makes this particular brand so special, to which she replied, "First of all, it's delicious, it's lower in calorie. It's also a little bit less proof so you can drink it straight."
"Especially the flavors, they're delicious," the soon-to-be 37-year-old added. "Raspberry cocoa, espresso vanilla fusion, orange vanilla fusion. It tastes like a creamsicle. Remember those popsicles you had when you were younger, the orange ones with ice cream in the middle? That's what the orange vanilla fusion tastes like. Just pour it over ice. Trust me. Trust me."
To cap off the visit, Fergie joined Jimmy behind a makeshift bar as the duo showed off their bartending skills while mixing up beverages using bottles of Voli.
