It's been an enchanted evening for two kmfm listeners who have both won prizes after calling into the station.

Self-confessed child of the 90s and massive Britney Spears fan Amber Stevens won kmfm's competition to see the star perform live in Las Vegas.

And mum Emma Goodacre, from Cheriton, pocketed £2,090 after guessing the fiendishly difficult Kent Sound that has been baffling listeners since April.

For those who missed the moment Emma cracked it, the Kent Sound was the noise of the HM submarine Ocelot's hatch.

Emma made the call from her parents house in St Margaret's Bay, near Dover.

Dad Gordon said: "She was over the moon when she guessed it. She'd had it in her head for a while and asked her mum what she thought and she agreed and tonight she got through."

And Emma's family could be in for a treat... she told DJ Ed Matthews she planned to spend the money on Christmas presents.

Meanwhile, Amber is looking forward to seeing Britney Spears at Planet Hollywood in Las Vegas.

The 22-year-old and her partner Sam Newman, 26, will spend four days in the luxury Venetian Hotel in the heart of the city, and as well as the concert, will enjoy a $250 shopping spree at The Forum Shops at Caesars or Las Vegas Premium Outlets.

Amber, from Kennington, Ashford, is herself an accomplished singer, and has been a Britney fan for as long as she can remember.

She said: I'm a huge Britney fan. I'm a child of the 90s so I grew up with her and she's always been a huge inspiration to me."

Last year the 22-year-old performed in front of 9,000 people at Rochester Castle as part of an event called Under Siege.

Amber found out about her win at work, prompting a massive cheer from workmates.

She said:"I'm one of those people who normally never wins anything so this has really blown me away."

And do the couple have any other plans for their time in Las Vegas?

"We're not going to do anything silly like get married," joked Amber.

"But it would be silly not to go into at least one casino while we're there, just to say we've done it."

Let's hope her lucky streak continues.
