The singer, 29, performed I Believe In Love on an Instagram Live feed, after taking time away from the limelight.
It’s been three years since she released Bang Bang with Ariana Grande and Nicki Minaj; topping charts in the UK and also giving her her biggest US smash to date.
Her third album, Sweet Talker, came out a similar time, after which she became a coach for two years on The Voice Australia and took herself out of the UK public eye.
Now, it seems she’s readying her fourth era.
Earlier this year, she said of the upcoming material: “Where I’m at with the new music, everything written thus far I’ve written by myself.
“Everyone who’s heard the album so far says it’s very honest and very grown. I’m speaking on issues that a 29-year-old goes through which is different from what I’ve sung about in the past.
“But I have to be true to what’s in my mind and heart. I’m working with one producer, DJ Camper, on this cohesive piece of work.
“It’s a piece of music as opposed to singles and album fillers.”
Jessie J released her debut single Do It Like A Dude in 2010 and has since racked up three Number Ones and seven Top 10 singles in the UK.
Her debut album Who You Are was a phenomenon; eventually being certified four-times Platinum in the UK.
However her subsequent releases have failed to hit the same highs, and Sweet Talker also received mixed reviews from music critics.
