The couple have been planning the wedding for more than six months now, reported Daily Express online.
They have spent millions refurbishing Chateau Miraval, their 35-room
retreat near the village of Correns in the heart of Provence.
'They are flying in 200 to 300 guests,' a source said. The guests include actors Matt Damon, George Clooney,
Johnny Depp and Tom Cruise.
Guests are likely to enjoy wines from Miraval's own vineyard, including an acclaimed light, flinty rose, Pink Floyd.
