Veteran rocker Alice Cooper and EastEnders actor Ross Kemp will be among stars competing in a celebrity golf event in August in south Wales.
Ant and Dec will again host TV coverage of the tournament
The event at the Celtic Manor Resort in Newport - home of the 2010 Ryder Cup - is the idea of TV hosts Ant and Dec.
It will again see Hollywood A-listers take on a team of famous Europeans over the August bank holiday.
Last year's televised event featured married couple Catherine Zeta Jones and Michael Douglas on opposing teams.
At the launch of the All Star Cup at the resort, there were also hints that a member of the Royal Family could take part.
Asked whether Prince William had been approached, the show's executive producer Bob Massie said: "Watch this space".
The European team, again captained by professional Colin Montgomerie, will be defending their title.
Ant and Dec, who will be hosting live coverage of the tournament for ITV1, said they were still in the early stages of putting the teams together but that experienced golfer Alice Cooper was "very excited" about it.
Dec said last year's event was a success because both teams took it really seriously.

"We had a nail-biting finish with Team Europe winning at the last hole by the narrowest of margins - only two points - so there really is everything to play for in the rematch," he said
Mr Massie said the celebrities would be "triple A-list stars". He said: "There is no Jade Goody here."
At the launch, Colin Montgomerie also said that although the celebrities were nervous last year the standard was very high.
Organisers are hoping radio and TV presenter Chris Evans will be back, but singer Robbie Williams was said to be busy on a world tour.
Last year's competitors, including rugby star Gavin Henson, football pundit Ian Wright and singer Ronan Keating, stormed to victory against an American team which featured Hollywood actors Michael Douglas and Patrick Duffy, and Olympic gold medal swimmer Mark Spitz.
About 20,000 spectators watched last year's tournament, although it proved a dangerous spectacle, with four players - Evans, Duffy, Cheech Marin and Hayley Osment - all hitting people in the crowd.
As part of last year's tournament, each competitor nominated a charity to benefit from their efforts.
