Catherine Zeta Jones and Michael Douglas will play on different sides
The keen golfers agreed to take part in The All Star Cup, to be shown on Sky One over the August Bank Holiday.
Douglas' US side will be captained by Mark O'Meara, while Colin Montgomerie heads the European team.
The idea was dreamed up by TV presenters Ant McPartlin and Declan Donnelly, who are executive producers.
They initially held talks with ITV about the show, but Sky outbid ITV for the right to broadcast it.
Ant and Dec have promised a "fantastic event" and said it "couldn't be more exciting".
Other names on the European team include media mogul Chris Evans, Charlotte Church's rugby star boyfriend Gavin Henson, model Jodie Kidd, singer Ronan Keating, and former Cold Feet star James Nesbitt.

Actors Hayley Joel Osment, Rob Lowe and saxophonist Kenny G are playing for the opposing US team.
The squads will compete over August Bank Holiday at the Celtic Manor Resort in south Wales - the venue for the 2010 Ryder Cup.
The All Star Cup will be presented by Terry Wogan, Kirsty Gallacher and Jamie Theakston.
Bob Massie, executive producer at TWI, which is making the show, said: "The players have now signed up and we are delighted with the calibre of names taking part.
"There will be plenty of talent out on the course and competition is likely to be fierce - make no mistake, both Europe and the US are playing to win."
