The hitmaker's kids are not old enough to vote, but the rap star wanted them to remember such an important day in America's history.
He says, "(I wanted) to show them how special our country is."
LL Cool J wasn't the only celebrity caught lining up to cast a vote - Tim Robbins, Ryan Phillippe, Selma Blair, Sean 'Diddy' Combs, Lindsay Lohan and Cynthia Nixon were also seen voting for a new president at the polling stations.
