October is National Breast Cancer Awareness Month, and Keith Urban is supporting the cause by donating a guitar for an auction to benefit the Susan G. Komen for the Cure foundation.

The guitar, (pictured), is a customized black Fender with the Breast Cancer Awareness Month signature pink ribbon. It will be slightly used by the time bidding begins at the end of October - Keith is playing it at all of his shows this month.

Other country stars are helping the Komen foundation this month. Jason Aldean donated more than $300,000 after a Virginia show last Friday, and Martina McBride is playing a benefit concert October 22nd at the Grand Ole Opry in Nashville.
