Coleen McLoughlin is promoting the draw to players in the UK
Next week's EuroMillions lottery draw will see another record jackpot up for grabs after no-one won this week's estimated £85m prize.
The draw, run by the National Lottery and operators in eight other countries, looks set to be worth £100m next week.
Ticket sales were running at quadruple the usual rate ahead of Friday's draw, UK organiser Camelot said.
The winning numbers in the draw were 12, 15, 33, 44 and 50. The Lucky Stars were two and six.
No-one won the prize for the 10th week in a row and the potential jackpot is now the biggest in European lottery history.
It beats the £79m won by Ireland's Dolores McNamara in the EuroMillions draw last July.
Players are required to match five main numbers from one to 50, plus two Lucky Star numbers from one to nine.
Coleen McLoughlin, girlfriend of England footballer Wayne Rooney, has been chosen to promote the draw in the UK.
The EuroMillions draw is also open to players in Austria, Belgium, France, Ireland, Luxembourg, Portugal, Spain and Switzerland.
Tickets for the draw can be bought in nine European countries
If a single UK ticket-holder had won the jackpot, they would have become the biggest winner in National Lottery history.
The UK's top EuroMillions jackpot winner is Marion Richardson, from Gateshead, who won £16.7m on 9 April 2004, two months after the game was launched.
The largest UK National Lottery jackpot win in history was £42m shared by three ticket holders in January 1996.
The UK's biggest single winner revealed to date is Iris Jeffrey, from Belfast, who won £20.1m in July 2004.
Proceeds from the EuroMillions tickets, which cost £1.50 in the UK, raise money for good causes.
