Christina Aguilera "excited" about PSA with son

In a Wednesday night appearance on Larry King Live, Christina Aguilera said she had no qualms about including son Max Liron, 5 ½-months, in her public service announcement for Rock the Vote. "As a new mother," Christina said, "I want the best possibilities for [Max], so I was excited about getting him involved." The 27-year-old songstress added that -- as someone who is constantly photographed -- she appreciated having the opportunity to expose Max in an environment of her own choosing.

What a great way to subject him to [the press] in such a positive way, in such a great time in history, to something as positive as getting people to vote and getting people to care about their country and getting people excited about this change.

Max is the first child for Christina and husband Jordan Bratman, who wed in 2005.
