Eliza Dushku is taking part in a charity walk next month (Sep11) to raise awareness of lupus.
The actress has signed up for the Lupus Foundation of America challenge in Los Angeles and she hopes to raise at least $1,000 (£625) for the organisation, which investigates the cause of the autoimmune disease.
Dushku states on her fundraising page, "I hope you will consider making a secure online donation to help me reach my goal! It's easy to do - just click on the link to support me and complete the donation process. I really appreciate your help! There is hope on the horizon, and with your help we can find better treatments and a cure."
And the star is encouraging her fans to take on the walk too, adding on her Twitter.com page, "Join US! I set a goal to kick some Lupus A**."
