The 'Laserlight' singer has agreed to return to the coaching panel for a £500,000 fee, says the Daily Star.
"Jessie has signed on the dotted line and will definitely be back for another series," a source told the paper.
"She did find some of it tougher than she expected but the positives outweighed the negatives so she's chosen to come back."
The 24-year-old's fellow coach will.i.am has said that he is keen to stay on for a second run of The Voice, despite ratings dropping by seven million over the course of the series.
The show's first series also featured coaches Danny O'Donoghue and Sir Tom Jones, whose act Leanne Mitchell went on to win the competition.
