The actor recruited his wife Fergie's band to headline a benefit show in his native Minot after heavy flooding forced 11,000 residents in the city from their homes earlier this summer (11).
About 16,000 fans turned up at the Minot Rising show at the North Dakota State Fairgrounds, where singer Fergie gave a shout out to the locals.
She told the crowd, ""This is a beautiful, beautiful vision for us, especially for me because I have family here now... It might be small, but it has the biggest heart in America. North Dakota, we love you so much!""
Her bandmate will.i.am later took to his Twitter.com page to recognise Duhamel's efforts in organising the fundraiser, writing, ""Thank you for you (sic) passion, determination, and vision to do good, and ability to bring people together for a good cause... BEP had a concert in N Dakota & raised 1 million dollars for Minot flood recovery.""
All proceeds will benefit flood victims.
