Callie wants to treat her family with the winnings
Teenager Callie Rogers was "jumping and screaming" when she realised she had become the National Lottery's youngest ever millionaire.
The 16-year-old, from Cockermouth, Cumbria, described the moment at a media conference on Tuesday, as she recalled when she realised she had won the £1,875,000 prize on Saturday.
Callie told reporters at the conference organised by lottery company Camelot she was dog-sitting for a friend when the draw took place.
She said she rushed home to check the numbers - 1, 10, 17, 23, 29, and 35 - which she chose on the basis of family birthdays.
Callie, who lives on a council estate with her foster parents, was one of eight winners sharing the £15m prize.
On Tuesday she posed for pictures with boyfriend Gary Fidler, 25, who was with her when her numbers came up.
And she said she was looking forward to taking her first holiday
She said: "Hopefully I will make us all comfortable. I want to help my family but I won't change.
"I'm still going to shop in the same shops and do the same things."
But Callie, who left school in December last year, said becoming a millionaire will mean a different future.
She said she was going to go travelling for two years, then would like to do GCSEs and become a social worker.
One of the first things she hopes to buy is a new wheelchair for her foster mother, Sheila Holmes, that will enable her to get up and down kerbs more easily.
She also plans to pay for grandmother Joan to visit her sister, whom she has not seen for seven years, in Australia.
"I will not go wild and spend loads. I'm going to take some advice and see an accountant."
Callie, who will be 17 in December, is going to treat herself, and said she wants to buy a Peugeot 206 convertible when she learns to drive.
She said: "My brother also wants a motorbike and my sister said she wants a suitcase to go on holiday with."
Callie has been working since leaving school in a number of jobs, as a shop assistant, a waitress, and at the Cockermouth Co-op, and she will be happy to take a break.
The teenager does the National Lottery every few weeks and always uses the same numbers. She buys a Lucky Dip as well.
