Motherhood has made Alicia Keys socially responsible

R&B singer Alicia Keys, who is expecting her second child with rapper husband Swizz Beatz, says motherhood has made her more passionate towards social issues.

Keys, 33, said she is now more dedicated to her organisation for eradication of AIDS in children, after she gave birth to her first child, four-year-old son Egypt Daoud, reported People magazine.

"Being a mother has definitely furthered my passion for Keep a Child Alive and just talking about issues in the world overall. My husband tells me, 'You should go lay down,’ but I can't. I'm inspired!" she said.
