'Britain's Got Talent' Winners Diversity Talk Susan Boyle

'When you are a solo artist it must be hard,' troupe leader Ashley Banjo says.

The dance troupe Diversity, who triumphed over Susan Boyle in the "Britain's Got Talent" final on Saturday, told Britain's Sky News

that it must have been "hard" for Boyle to deal with the pressures of overnight fame by herself.

"Susan must have a lot of support from her friends and family," Ashley Banjo, the 11-member group's leader and choreographer, said. "But we're in this together as a group and we are really close, so when you're on the stage, when you're doing interviews in the media spotlight, you've got each other.

"When you are a solo artist it must be hard because you've got a lot of pressure to deal with on your own."

Boyle showed signs of strain in recent weeks and on Sunday was admitted to a mental-health clinic, suffering from exhaustion.

Banjo, 20, said the group — which includes three sets of brothers and friends between the ages of 13 and 25 — nearly "died of shock" when they learned they'd won.

"As the show unfolded and Susan Boyle became such a huge star, I didn't think we'd beat her," he said. "We were just happy to get to the final."

"I think I fell over," Banjo said during a press conference after the show, according to Reuters.

"I had my speech ready, you know, 'Well done, Susan.' Then they said 'Diversity,' and honestly, my legs actually gave way. I'm really tall and there's a long way to fall. I hit the floor, and honestly words can't describe how I felt."

Banjo said of Boyle, "She was so gracious about [Diversity's victory], she said the best act won and [backstage] she said she saw something special.

"She was so nice about it. She has a great career. She's going to do really well anyway."

The troupe will perform on the "Britain's Got Talent" tour later this month, and will perform for the Queen at the Royal Variety Performance in December. They will also appear with Kanye West and Kelly Rowland at Britain's Wireless festival on July 5.
