in 1999 Rai starred in Sanjay Leela Bhansali's Hum Dil De Chuke Sanam, opposite Salman Khan and Ajay Devgan. The film had Rai playing Nandini, who is forced to marry Devgan despite being in love with another man (Khan). Her husband tries to help her locate her previous love, and his caring attention eventually wins her over. Rai's portrayal won her critical acclaim, with a review on Rediff.com stating, "Aishwarya looks beautiful as usual ... This film will most likely draw her accolades from all over, may be even get her recognised as an actress the way Manisha Koirala did in Khamoshi. In many scenes, there is no trace of makeup and she looks very fresh". The film was her first box office success in Bollywood, and earned her a Filmfare Best Actress Award.
