The 'Back to Black' star is currently rehearsing for the five shows that she'll play in the South American country, including performances in Rio de Janeiro and Sao Paulo.
A source told The Sun: "Amy will be rolling in it. Brazil is keen to establish itself as a major player in live music and is attracting a host of top stars.
"A lot of money is being thrown around to secure their services and it's working."
The singer also has a show planned next month in Dubai as part of Gulf Bike Week.
