Taylor Swift is donating $US1 million ($A1.30 million) to Louisiana after torrential rains caused massive flooding and killed at least 11 people.
The American singer-songwriter has told the Associated Press she has been heartbroken watching as residents have been forced to flee their homes.
She says when she toured the state last year the residents made her feel completely at home and she's encouraging others to "help out and send your love and prayers" to those suffering.
The flooding is some of the worst in Louisiana history, damaging at least 40,000 homes.
More than 60,000 people have registered for disaster aid from the Federal Emergency Management Agency after widespread flooding hit the state.
