In the Mega Millions prize draw last night, one lucky ticket holder matched all six numbers and won the jackpot.
The winning numbers were: 5, 28, 62, 65, 70 with the Mega Ball being 5.
The staggering $1.6billion (£1.2billion) prize was so large as no-one had won for nearly three months.
The last winners were a group of 11 colleagues, who shared $543 million between them.
