Randy Jackson has a knack for business, dawg. Word on the street is he's cornering the market on eyeglasses for men with abnormally big heads. His line, which was probably born out of his own lifelong difficulties finding a pair of glasses that didn't dig into his temples, is apparently "flying off the shelves." Says a "retail spokesperson," "The line launched two months ago, and they've been totally overwhelmed with requests. It's hard for men with large heads to get eyeglasses to fit right, so the Randy Jackson line really filled a void. They are so in demand that the only prescription frames harder to get right now are Chanel." No word on whether he's going to expand his line to include glasses for women with big heads and men with extremely tiny faces.

As odd as Randy Jackson's latest business investment sounds, he's not the only celebrity to venture into realms that have nothing at all to do with their main jobs. I mean, how did boxing prepare George Foreman for boundless success in the counter-top grill business? Besides the well-publicized clothing lines, record labels, and production companies, a lot of actors, musicians, and athletes like to use their resources to pursue their diverse interests.

To name a few, Lenny Kravitz started a design firm called Kravitz Designs, Melanie "Scary Spice" Brown runs Chi Phoenix Lofts in downtown LA, Queen Latifah owns a string of Fat Burger franchises, 50 Cent's coming out with his own condom brand called Magic Stick Condoms (yawn), and Patti LaBelle, predictably enough, launched her very own line of wigs (watch out Beverly Johnson!) at the beginning of the year. Oh, and we all know about Lil Jon's fabulous wine.
