The 'Domino' singer took to Twitter earlier today and announced her decision to leave after serving as a coach for two series', adding that her music "has to take priority".
She said: "I've absolutely loved my time on The Voice, and I hope everyone saw and knows how passionately I felt about the show.
"I can't wait to promote my new record around the world and that has to take priority. I shall be keeping a very close eye on series three, showing my support in every way I can, and really hope that in some way that I can be part of the show.
The BBC are now on the search for an artist to replace Jessie for the third series, while Sir Tom Jones, Danny O'Donoghue and will.i.am remain.
Mark Linsey, BBC controller of entertainment commissioning, said: "We're so sorry to see Jessie go as she's been an exceptional coach on - and advocate for - The Voice, but we totally support her decision to leave due to touring commitments overseas.
"We very much hope that Jessie will remain part of the show and come back and perform for us next series.
"In the meantime, we will now start the search for a new coach."
