Toni explained to hosts Reggie and Holly beforehand how she had gone bold in her twenties as a result of her Alopecia, which has led to a lack of confidence.
But a mesmerising performance of Will Young's Leave Right Nowon The Voice UK stunned the coaches to get three of them to turn around and ask her to join their teams.
The singer, who previously saw fame when taking part in Opportunity Knocks back in 1987 as a youngster, won over Danny O’Donoghue, Jessie J and Sir Tom Jones, with only Will.i.am not turning around.
It of course left Toni with a tough choice, having to decide between the trio of superstar coaches and pick just one to join for the rest of the show.
"I could tell you've been through pain and that's what moved me emotionally to press my buzzer," Danny said.
Jessie told her: "Your tone is so old school, I feel that you could teach me something. Please let's hang out and make music."
Sir Tom added: "You are a real, real singer. You sound fantastic."
Making her decision, Toni said: "Four years ago I heard Jessie J for the first time, and Jessie, I would love to choose you!"
