Singer Taylor Swift spent $6,000 for Hugh Jackman's t-shirt, all for charity.

The 25-year-old took part in an auction benefiting Broadway Cares/Equity Fights AIDS after attending Jackman's Broadway show "The River" Wednesday afternoon, reports aceshowbiz.com.

The t-shirt, which the Australian star wore during his performance, was one of the items auctioned off for charity. Apart from the sale of the t-shirt, Jackman even raised an additional $6,000 from another audience member and threw in $6,000 himself. Another audience even offered $2,000 for his belt.

Swift and Jackman later posed together backstage at the Circle in the Square Theatre in New York City.

“Lovely to see @taylorswift13 and her family. Merry Christmas Eve to all xoxx,” Jackman captioned the photo he posted on his Instagram page.`
