Swift told The Associated Press on Tuesday that Louisiana residents graciously welcomed her when she kicked off the U.S. dates of her "1989 World Tour" in the state last year.
"We began The 1989 World Tour in Louisiana, and the wonderful fans there made us feel completely at home. The fact that so many people in Louisiana have been forced out of their own homes this week is heartbreaking," the 26-year-old said in a statement.
"I encourage those who can to help out and send your love and prayers their way during this devastating time," Swift said.
WATCH: Local volunteers headed to help in Louisiana flooding
Louisiana Gov. John Bel Edwards' office says more than 60,000 people have registered for disaster aid from the Federal Emergency Management Agency after widespread flooding hit the state.
Devin George, state registrar for vital records, said Tuesday the latest confirmed death occurred in Rapides Parish. He did not immediately provide details.
Of the other deaths, five were in East Baton Rouge Parish, three in Tangipahoa Parish and two were in St. Helena Parish.
Floodwaters were receding in many parts of south Louisiana on Tuesday, though they were continuing to rise in other areas as the water drained south.
