The singer has unfortunately had to battle breast cancer twice, first in 2003 and then again in 2013 when she had to undergo a double mastectomy.
US performer Anastacia says she wants to "give as much as I can back to the women and to a cure" in a bid to "make a difference.".
"I'm going to try to ask as many of my mates that might have a couple of extra dollars to match what I make," Anastacia added to the BBC News website. "So whatever I end up making I just want them to match it."
And the donation also gives Anastacia an extra incentive to do well in the competition
"I’m going to go for it because I’m donating everything to breast cancer, so I have an end goal which is – they get more money," she said. “That’s the deal. If I get kicked out, they don’t pay much, so they’re not going to get much.”
Speaking last week during the red carpet launch of this year's Strictly, Anastacia revealed how beating breast cancer twice actually inspired her to sign up for the show.
“I don’t know that I was ready for it prior to the mastectomy. I was insecure to do the show and fail and not be as good as I want to be," she explained.
The Left Outside Alone hitmaker went on: "I think that once you go through a life-altering situation, where part of your natural female situation has changed, it sort of brings you down to earth. You go, ‘I’ve removed a body part. What more is there to be nervous and scared about?’”
Anastacia has been partnered with Brendan Cole on the line up and will perform live for the first time at the end of the month.
