Aishwarya is Hindu and deeply religious. Her favourite temple is a 200-year-old Lord Ganesha Temple.
In 1999 Aishwarya began dating Bollywood actor Salman Khan; their relationship was often reported in the media until the couple separated in 2001. Rai cited "abuse (verbal, physical and emotional), infidelity and indignity" on the part of Khan as a reason for ending their relationship. However, in a 2009 Times of India article titled "Salman didn't hit Ash!" Khan denied ever beating her: "It's not true that I hit a woman."
Rai is married to actor Abhishek Bachchan. After much speculation concerning their relationship, their engagement was announced on 14 January 2007. The announcement was later confirmed by his father, Amitabh Bachchan. The couple got married on 20 April 2007 according to traditional Hindu rites of the Bunt community to which she belongs. Token North Indian and Bengali ceremonies were also performed. The wedding took place in a private ceremony at the Bachchan residence "Prateeksha" in Juhu, Mumbai. Though the wedding was a private affair intended for the Bachchan and Rai families and friends, the involvement of the media turned it into a national extravaganza. They have been cited as a supercouple in the Indian media. Rai has been very close to her family and lived with them in Bandra, Mumbai, until her marriage.
