Happy Birthday, Nick Cannon!

You know who is going to have a really, really good day today? Nick Cannon, who will be celebrating his 30th birthday. The actor, rapper, television mogul and husband to Mariah Carey has crammed in an awful lot of bullet points on his resumé in his first three decades on the planet, and you never hear anybody saying anything bad about the guy — a rare combination for a young, rich media mogul.

Cannon got his first big break way back in 1998 when he became a featured player on the hit Nickelodeon show "All That" (he was discovered doing stand-up comedy, which he began doing in his early teens). His success on "All That" lead to a string of future television opportunities, including his own Nickelodeon vehicle ("The Nick Cannon Show") and a series of hits on MTV (including "Nick Cannon Presents: Wild 'N Out," the extremely entertaining improv comedy competition show). The film world also came calling, as Cannon has headlined hits like "Drumline," "Love Don't Cost a Thing" and "Roll Bounce." But he always came back to television, and currently serves both as the host of the hit reality competition show "America's Got Talent" and also acts as the chairman of TeenNick, where he develops new programming for the network.

Cannon's career as a rapper was unfortunately brief, as it consists of only a single album (his self-titled 2003 debut) and a handful of guest appearances. But Cannon's smooth flow and sly boasts made him especially suited for head-nodding crossover tracks like "Gigolo," the biggest single from Nick Cannon that also featured a drop-in from R&B mastermind R. Kelly.
