BEYONCE, JULIANNE MOORE and JENNIFER LOPEZ have joined forces to help U.S. leader BARACK OBAMA pick up the female vote at November's (12) presidential election.

The trio and other leading ladies are urging female voters to keep Obama in the White House for another four years in a new TV ad.

R&B superstar Beyonce claims her political pal "has the story that I can tell my daughter, because it shows that no matter where you start out, you can work hard and you can do whatever you put your mind to."

And Lopez adds, "Women will help decide this election."

The Women for Obama video also features Eva Longoria, Jane Lynch, Sheryl Crow, Ashley Judd and Olivia Wilde.
