Keira Knightley is set to tie the knot at her family's $5 million French vineyard.

The 'Anna Karenina' star will reportedly marry her rocker fiance James Righton today (04.05.13) on the grounds of the eight-bedroom property in Mazan, a village near Mont Ventoux in Provence.

A source told the MailOnline website: ''It's a beautiful location for the wedding. They're very, very lucky. It's just the perfect time of year for it as well, they couldn't have picked a better weekend weather-wise.''

Several marquee tents have been erected on the sprawling farm and the couple have employed a local catering team for the reception, during which guests will indulge on 120 bottles of wine sourced from local vineyard Chateau Minuty.

The 28-year-old actress reportedly bought the estate, which is covered in olive trees, in 2010 but it is in her playwright mother Sharman Macdonald's name, who is also registered as the chief winemaker there.

Keira, who is set to wear a custom-made dress by Chanel designer Karl Lagerfeld, was spotted greeting rocker James with a passionate kiss after driving to Nice Cote d'Azur International Airport to pick him up from his flight on Tuesday night (30.04.13).

The couple will exchange vows in front of 50 close friends and family members.

A previously said: ''It's all been a massively covert operation - her friends and family were only told recently about the ceremony.

''They've all been told not to travel in big groups, to arrive separately and to all spread out where they're staying so as not to draw attention to the wedding party.''

The couple got engaged in May 2012 after meeting through mutual pal Alexa Chung, and Keira recently moved into a new home in East London with the 29-year-old Klaxons keyboardist.
