Sunanda was 52 years old and has a 21-year-old son from an earlier marriage.
Tharoor allegedly informed the police of his wife’s death on Friday, NDTV reported quoting the Press Trust of India (PTI).
Sources said a suicide note has not been found.
Tharoor tweeted at 8:01pm Friday that he would not attend the Jaipur Literature Festival because his wife was unwell.
On Wednesday, in a series of tweets, she had accused the Pakistani reporter, Mehr Tarar, of “stalking” the minister.
That evening, she told NDTV on the phone that she planned to seek a divorce and was “heart-broken”, details were not reported by NDTV because it was seen as a private matter. She said she wanted to do an interview with NDTV.
In a phone interview on air on Thursday, she said she was happily married, but reiterated her charges against Tarar.
The couple then issued a statement which said they are “happily married” and intend to stay that way.
The statement added that Sunanda was unwell and sought privacy from the media.
The Tharoors were married in 2010.
A few months before their wedding, Tharoor was forced to resign from his first ministerial post after allegations that Sunanda, a Dubai-based entrepreneur, had been given free stake worth 50 crores in the new Kerala team for the cash-rich Indian Premier League.
Opposition parties alleged that the “sweat equity” worth an alleged 70 crores, was actually a payment to Tharoor for behind-the-scene services for arranging the sale of the team in his home state to a consortium.
