The three-storey townhouse in Cobble Hill, Brooklyn served as the home of Roberts' real-life character, Elizabeth Gilbert, in the 2010 romantic drama, which was based on author Gilbert's memoir of the same name.
The pad, a former 1840s firehouse, originally went on the market for $7.9 million (£4.94 million), but the price was slashed for a quicker sale and it was offloaded for $6.25 million (£3.9 million).
Realtors refused to identify the mystery buyer at the time of the sale, but now it has been revealed notoriously-private Jones was the one who purchased the pad, which had been transformed into a two-unit home, according to the New York Daily News.
The Brooklyn-born Come Away With Me singer, who became a first-time mother last year (14), reportedly intends to convert the building back into a private mansion.
Jones, the daughter of Indian sitar player Ravi Shankar, is no stranger to the Cobble Hill neighbourhood - she also owns a house nearby, which she picked up for $4.9 million (£3 million) in 2009.
