The 40-year-old mother of one will now walk the red carpet on an alternate day after her flight from London to Nice was delayed.
The former Miss World is regular at Cannes, thanks to her stint as L'Oreal Paris ambassador, and has been attending the ceremony on behalf of the brand for 13 years.
The team is making arrangements for Aishwarya's walk on the red carpet on some other day.
"Aishwarya Rai Bachchan is truly a global icon for L'Oreal Paris and while the delay has been unfortunate, we are making sure that Aishwarya attends the event on an alternate date and we are sure she will dazzle as always," Manashi Guha, General Manager L'Oreal Paris India, said in a statement.
The other Bollywood celebrity to attend 67th Cannes Film Festival is Sonam Kapoor. Actress Mallika Sherawat walked the red carpet yesterday in a blue Emilio Pucci gown.
