The 31-year-old singer played an as-yet-untitled track for her fans during a small concert in Los Angeles over the weekend.
The lyrics were: ''Where you go I know I want to follow, let's make a promise today. Let's be still, just stay calm, so we're not rushing what we are. Pressure on, just have fun, it's not a race, no need to run, if it's for ever, let's just simply be in love.''
Meanwhile, Jessie J previously revealed she is taking a break from Instagram.
She wrote on the social media site: ''For the record I'm OK. Happy, healthy and sane. People often presume to come off Instagram you are going through some s**t. Lol. Actually it's the opposite. Im in such a good place that I want to respect and nurture that looking up and not looking down. Instagram is fun, but it isn't real life.
''I'm off to write a new album. Telling just the people who support me. Love you all. Be back soon. Refreshed and refuelled and ad-libbing OBVIOUSLY ... (Also try and instagram cleanse every once in a while - it can do you no harm) (sic)''
And Jessie had revealed she took time away from the music industry so she could ''heal'' her own wounds.
She said: ''In the two years that I did 'The Voice' in Australia, I was diagnosed with some health issues that I'm not ready to talk about that I had to really face as a woman. I also lost my grandparents and didn't have time to grieve.
''The hardest part about being an artist is that you have to open your wounds to heal other people's and you don't often get the time to heal your own.''
