Singer-songwriter John Legend will headline a Procter & Gamble Co. promotion to benefit dropout prevention as part of his broad support of education reform.

Legend has made commercials that will air ahead of P&G coupon inserts with him on the cover that will be in newspapers on July 31. The promotion by the Cincinnati-based consumer products giant also will include Facebook and other online efforts to raise money to help children stay in school.

Legend has focused much of his charitable work on education improvement. He says making sure that every child has access to a quality education is key.

The Springfield, Ohio, native is concerned about what he calls politically motivated efforts to weaken teachers' unions in Ohio and other states.
