The much anticipated collaboration between Christina Aguilera and Rock The Vote has finally been unveiled. In the brand new public service announcement the 27-year-old songstress is seen gently rocking her now 6-month-old son Max Liron, swaddled in the American flag, as she sings ‘America The Beautiful’ a capella.

Max is the first child for Christina and her husband Jordan Bratman.
