Many people celebrate their 19th birthday by throwing a party, going out or seeing friends and family.
But few reach the milestone by becoming a millionaire.
Deisi Ocampo, from Chicago, scooped a staggering $4million on the Lottery on the day she turned 19.
The teenager had received two Illinois Lottery scratch-off tickets, each worth $20, as a birthday present from her father, who had bought them at Austin & Montrose in West Montrose Avenue.
At the time, he had wished her a 'happy birthday' - not knowing how happy it would turn out to be, Eyewitness News reported.
'It turned out to be the best birthday present ever,' said Miss Ocampo following her incredible win.
On Friday, the teenager was presented with a check at a gas station on Chicago's Northwest Side, according to News 4 San Antonio.
She said she plans to use her winnings to 'buy a new house for my family and pursue my dream of completing my degree and becoming a nurse.'
Miss Ocampo won her millions in a game called $100 Million Money Mania, which offers players the chance to win prizes from $100 to $100,000, or a $4,000,000 top prize.
Players must match any of their numbers of a winning number to gain the prize shown for that number.
