Hot competition: Britain's Next Top Model finalists show off glamorous new looks ahead of live final

The live final of Britain's Next Top Model takes place on Monday, but Joy McLaren, Alisha White and Tiffany Pisani showed no sign of nerves as they debuted their glamorous new looks in London today.

Tiffany, who had sported a peroxide pixie crop throughout the series, had transformed most dramatically, showing off a new brunette bob.

Joy's bob, in turn, was longer with a sweeping fringe, while Alisha lent a sophisticated edge to her super short do with oversized pearl earrings.

It has been several months since filming ended, though the last episode, in which the trio walked the catwalk in Malaysia for designer Bernard Chandran, only aired this week.

At the final elimination, the show's host and chief judge Elle Macpherson, said: 'I can't decide'.

Now viewers will choose which of the three girls most deserves to win the competition.

The successful girl will appear on the cover of Company magazine, the chance to appear in a Revlon campaign and a contract with modelling agency Models 1.

Model behaviour: The trio showed no sign of nerves ahead of the Britain's Next Top Model live final next week

In interviews with Living TV ahead of next week's show each girl talked about their experiences on the show, and how they felt about the judges.

'I'm extremely excited about the live final,' said Tiffany. 'I'm excited, I'm nervous, I'm happy, I don't know what to expect. I have no idea who is going to win and I'm dying to find out.'

She admitted that her lowest point was when she was made to cut her long blonde hair, but she's proud of how she's learned to accept her new look.

'Now i'm really happy that I cut it,' she revealed. 'It was a big learning curve for me because I was very attached to it and it was a big part of my personality.'

Alisha admitted that she felt Amelia should have been among the final three: 'If I could change the final three, I would put Amelia in it because I think she's got that model look about her.

'I don't know who I'd swap her with,' she added.

But Joy said that her fellow finalists, selected by a panel including stylist Grace Woodward and designer Julien Macdonald, were the right choice.

'When I first went into the house, Tiffany stood out for me and so did Alisha,' she said.

She added that she was most excited about the idea of winning a Revlon campaign: 'Revlon is a brand I've known all my life - it would be a real honour, especially because it's always celebrities nowadays. It's harder for models to get these campaigns,' she explained.

But for Alisha, the coup would be working with a top modelling agency.

'I'm excited baout wining every prize,' she said. 'But obviously signing that contract and being part of Models 1 would be like: "Oh my God, I'm officially a model now!"'
