Celebrity: Britney Spears

Product: Nokia 5800 XpressMusic

Britney Spears normally limits endorsements to products that bear her own name or likeness. But she incorporated Nokia's 5800 XpressMusic phone into her "Womanizer" video as part of a product placement deal. In the video, her love interest is the one who actually uses the phone, first to check his calendar and, later, to film her dancing.
