Dolly Parton has received a "tremendous boost" in songwriting royalties for her track I Will Always Love You following Whitney Houston's death.
Houston's 1992 version of the ballad, which Parton wrote in the 1970s, returned to the top of the charts after she died in February, as fans flocked to purchase her signature hit.
The country icon previously said she was left "shattered" by Houston's death, and now she has revealed she netted a fortune from the international smash.
"I've had a tremendous boost in finances since Whitney passed on because there have been lots of new Best Of albums and different people recording the song," Parton told Britain's Daily Star Sunday.
"It really did boost sales. I am so thankful to God for that and to Whitney who did such a good job with it. She made the song go worldwide when it was first released. It's a song which keeps me in wigs, hair and make-up."Parton, who is said to be worth an estimated $US400 million ($A389 million), adds: "I still need to work - I have a big family to support. Nobody ever makes that much money, not the kind of money I spend anyway."
