Bruno Mars launches US tornado auction

Bruno Mars has launched an auction of concert memorabilia intended to raise funds for victims of the recent US tornadoes.

The 'Lazy Song' artist revealed on Facebook that fans could support the American Red Cross relief effort sparked by last month's disasters in the Southern states by bidding for some "very special" items.

The post read: "Bruno is auctioning off some signed & rare items to benefit the victims of the massive tornadoes in Alabama. ALL proceeds of this auction will go to the Alabama Tornado Disaster Relief Fund via The American Red Cross. Anything you can do to help would be most appreciated!"

The bundle of prizes includes a framed poster from Mars's "coming home" show in Hawaii last December, a limited-edition boxset of his debut album Doo Wops & Hooligans and lifetime membership to his fan club.

The auction closes on Thursday evening.

Other stars helping to raise funds for tornado victims include Charlie Sheen, David Spade and Kenny Chesney.

Lady Antebellum and Keith Urban were among the stars to perform at the Music Builds: CMT Disaster Relief Concert in Nashville earlier this month.
