Rocker Tom DeLonge has decorated a plaster cast of his wife's breasts to raise money for a cancer charity.

The former BLINK 182 member has lost a number of relatives to breast cancer, so he was delighted to contribute to an auction for the Keep A Breast Foundation.

DeLonge's cast of spouse Jen's bust includes a sketch of a city skyline and the words "I heart boobies, they will bring peace to our world. I heart boobies, they shall be my dinner."

DeLonge says about his contribution, "Never before has a non-profit organisation touched me like Keep A Breast.

"Like millions of others I have been plagued by the devastating effects of breast cancer hitting not one, but multiple members of my family."
