Beyonce, 31, mother to daughter Blue Ivy, nearly nine months, said in the Women for Obama campaign message that she is supporting the President for her daughter's future, reported US magazine.
"It's not just about supporting the President because I want to see him reelected, I'm standing up for the future of my daughter. The future that I want her to see," she said.
"Women will help decide this election. I grew up with a strong, hardworking mom and dad, and two brilliant sisters. I learned from an early age that when women come together, there is nothing we can't do," said Lopez.
Longoria, 37, who spoke at the 2012 Democratic National Convention, added, "I find such a champion in President Obama -- which is why I passionately support him -- specifically because I'm a woman."
