Despite admitting to being competitive with her rival coaches, the Domino hitmaker said this week that she was keen just to give her acts an opportunity.
The Voice UK sees each of the show's coaches - Jessie, Sir Tom Jones, Danny O'Donoghue and Will.i.am - pick ten budding performers to join their team. These will then be whittled down to just one finalist in each of the four teams by the last live show in June.
Revealing her coaching style, Jessie said: “I’ve been very, very conscious of the fact that I spend as much time as I can with them off camera. I’m really honest with them, it’s the only way I know how to be.
“It’s no good telling them what they want to hear. I’m here to help each and every one of them. I think I’ve got a couple of contenders who can win it but that’s not what I’m about.
“I’ve got to know them and I’m emotionally attached to all of them."
Jessie went on say that the artists had the "world at their feet" and needed to make the most of their opportunity.
And the 23-year-old said she could relate to the acts who will see overnight fame once they appear on the show: “It’s a very scary thing to step into something where everyone is going to know your name. Obviously I can relate to that.”
But despite the boasting, Jessie insisted: "I’m not so much about the winning.
"Realistically, we’ve only seen a fraction of what they can do. It’s going to be about the live shows for me.”
The Voice UK continues next Saturday on BBC One.
