The Bollywood actor told her Twitter followers that she wed partner Peter Haag in a private ceremony in Europe.
Jaitley posted: "With great pleasure I would like to announce my wedding with @peterhaag on the 23rd of last month at a thousand year old monastery in Austria.
"We seek your blessings and good wishes, and apologise for the delayed announcement due to a family tragedy."
The star also shared images from the ceremony, which saw Jaitley wearing a floral sari and holding a bouquet of red roses.
The performer recently denied reports that she was a lesbian, following her high-profile support of the gay rights movement in India.
Jaitley was rumoured to have secretly married her hotelier boyfriend at a ceremony in Dubai last year.
The model-turned-actor, whose image has been compared to US singer Katy Perry, was last seen in 2011 ensemble comedy Thank You.
