Alicia Keys is giving U.S. President Barack Obama's 2012 re-election campaign a big boost by speaking at a special event in Pennsylvania next week (begs16Jul12) to rally support from female voters.

The Empire State of Mind hitmaker will address attendees at the Women 2012 Vote Summit in Philadelphia on Monday (16Jul12) and encourage ladies to become more politically active.

Keys wants her fellow females to make their voices heard in the upcoming elections as their votes will be key in the race for the White House between the Democrat or his Republican rival, Mitt Romney.
