New York, July 13 - If you took a walk in midtown Manhattan during lunch hour on Wednesday, you may have noticed a really pretty woman surrounded by toothbrushes at the Times Square Studios on Broadway. Nope, you weren't seeing things. That was Halle Berry, and she was the center of attention when Oral-B introduced its vibrating toothbrush, Pulsar. In celebration of the new, um - gadget? Oral hygiene product? Toothbrush? We'll go with toothbrush - toothbrush, Halle forked over Oral-B's $150,000 donation to the American Heart Association. After her bit, Halle stepped right up to those open-to-the-street windows and greeted fans. We did not see anyone ask her to autograph their toothbrush.
