Jermaine Jackson backs Tesco Mary

Jermaine Jackson has tipped Tesco worker Mary Byrne for glory on The X Factor.

The Jackson 5 star said that Irish singer Byrne was his favourite performer from the first two live shows, describing her as "incredible".

Speaking to Konnie Huq on the Xtra Factor about his favourite act, he said: "I think it's going to be Mary. When Mary sings, you feel her. She sings from her heart. She's very sell-able. She can really sell her feelings. She's just incredible."

The pop icon also advised girl group Belle Amie that they need to "gel" and "come together" if they are to avoid being in the sing-off again.

"When you have four or five performers on a stage, you watch them all and they all have to be into it. But a few are not connecting yet," he said.

"They need to gel together and come together. It comes from time and working hard at it. They need to know what each other person is doing without even looking at them."
