Aerosmith frontman Steven Tyler just made a huge contribution to his charity.

Tyler put his 2012 Hennessey Venom GT Spyder up for auction to help raise money for Janie’s Fund. Janie’s Fund is a philanthropic initiative created by Steven Tyler in partnership with Youth Villages, to bring hope and healing for vulnerable girls who have suffered abuse and neglect.

The vehicle went for $800,000 – and along with the vehicle, Tyler threw in a guitar autographed by the band and offered the successful bidder a stay at his Hawaii home.

Tyler says in a statement: “We raised enough tonight to provide 20,000 days of therapeutic support to abused girls across America.

“As a father to three daughters, a son, and now a grandfather, it broke my heart to learn that each year in America alone, 700,000 children are victims of serious abuse or neglect – and 68,000 will be sexually abused.

“Together through Janie’s Fund, we’re helping girls rebuild their lives and overcome the trauma they experienced.”
