File this one under anything to make a buck. We can handle a Bono iPod, or an Armani cell phone, but a Miley Cyrus Toothbrush? The harder you brush, the louder it “sings” for up to a total of 2 minutes of “Pumpin’ Up the Party.” We’re not sure we can deal with that much of the tween idol at one time, but thank goodness after you invest in the brush for $9.99, both the brush head and batteries are non-replaceable. Ashley Tisdale and Hilary Duff models are also available at Hasbro. We think we will wait for a more rocking version, perhaps with the Stones’ “Mother’s Little Helper.”
