The wedding between Russell Brand and Katy Perry is to take place at a luxury resort outside the Ranthambhore tiger sanctuary near Jaipur, an Indian tour operator has said.
Rajasthan Tours manager Mohan Singh said his company was one of several involved in organising the six-day celebration that begins on Saturday with a Hindu wedding ceremony.
Mr Singh said the British actor-comedian and the US pop star have hired 13 vehicles to take some of their 80 or so guests on tours of the tiger sanctuary in the days after the wedding.
He said the couple would stay in a luxury tent at the Aman-i-Khas resort, with guests staying at the nearby Vanyavilas and Sher Bagh resorts.
Private security has been stationed at the hotels, which have refused to discuss the event with media.
"This would be a colourful Rajasthan wedding, and both Brand and Perry would be attired in Indian wedding attires," Mr Singh said.
Local police said they had not been informed of the impending nuptials. "We have no clue about the celebrations. But we would not allow playing of musical instruments and blaring loudspeakers after 10 in the night," Sawaimadhopur district police chief Vishnu Kant said.
Fireworks and other loud noises that might disturb guests or wildlife are also ruled out. "We are bound by the Indian laws," the police chief said.
Hoping to keep the event details secret, the couple had sent out wedding invitations saying simply that they were getting married in India and the celebrations would last for up to a week.
Comedian and actor Brand proposed to Perry in India outside the Taj Mahal while the pair were enjoying a romantic holiday in December 2009. Perry, 25, has appealed for privacy on Twitter.
