Does anyone remember Nick Cannon's early rap career? No? Neither do we, but somehow, we can't imagine his lyrics were particularly gangsta. The singer-rapper-actor is far more famous for hosting various television and radio shows -- and being Mr. Mariah Carey -- than he ever was for his thug attitude. Whether he's dressing up to match Mimi's over-the-top ensembles, inviting the media to photograph their annual vow-renewal ceremony, or cracking ridiculous, family-friendly one-liners as the host of "America's Got Talent," Nick is clearly one of the biggest cheese balls in the business.
