Need to push your product on the masses? What better way to do it than with a veritable army of celebrity spokespeople? This seems to be Microsoft's line of thinking when it comes to Windows Phone 8. They've lined up not just one or two celebrity endorsements, but closer to a half dozen, and those include some pretty big names.

Microsoft already had Jessica Alba extole the virtues of Windows Phone 8 at their launch event, and more celebrities like her haven't been far behind. Microsoft just pushed out two spots, one that features Holly Willoughby, and another with Arrested Development alumnus Will Arnett, but that's only the beginning. The Sun reports that Jay-Z, Gwen Stefani, and James Corden are also hopping on the Windows Phone 8 ad bandwagon.

This seems to be right in line with Microsoft's big all-or-nothing ad push for new Windows 8-related devices, but only time will tell if Lumia-wielding celebrities will pay off big or not. In the meantime, sit back and place your bets; who's coming next? [The Sun, The Verge, The Next Web]
