Actress Catherine Zeta Jones and her husband Michael Douglas are on opposing sides in a celebrity version of the Ryder Cup.
The Welsh star has been confirmed to play on Colin Montgomerie's European team on the Sky One show.
Douglas's US side will be captained by Mark O'Meara, and has Hollywood actor Rob Lowe on board.
The idea for the tournament, which takes place over the August Bank Holiday, was dreamed up by golf fans Ant and Dec, who are executive producers.
Other names on the European team confirmed today include Chris Evans, Charlotte Church's rugby star boyfriend Gavin Henson, model Jodie Kidd, former Cold Feet star James Nesbitt, and Irish singer Ronan Keating.
The All Star Cup will be presented by Terry Wogan, Kirsty Gallacher and Jamie Theakston.
A practice day will take place on Saturday 27 August, followed by two days of competition.
