Next month's benefit concert at Madison Square Garden for victims of Sandy received some added star power.

Jon Bon Jovi, Eddie Vedder and The Foo Fighters' Dave Grohl are now slated to perform at the Dec. 12 show.

They're joining a lineup that already includes Bruce Springsteen, Billy Joel, Paul McCartney and Kanye West.

Proceeds of the so-called "12-12-12" concert will go to the Robin Hood Relief Fund and benefit those affected in New York, New Jersey, and Connecticut.

Tickets go on sale Dec. 3 at noon.
