Janet Jackson's longtime BF, rapper/producer Jermaine Dupri may be short, but he's long on insults when it comes to Justin Timberlake, Page Six reports. (Guess he's not over the whole JT not standing up for Janet during Nipplegate.) In his new autobiography, Young, Rich and Dangerous, JD writes, "I think Justin Timberlake is a talented performer. But he's very ordinary-looking. He could be any skinny white kid from the suburbs of Orlando. You could go to the mall and find another Justin. He doesn't make his style interesting even when he's onstage. To me, he just doesn't look like a star." Uh, we'd take JT over JD any day of the week!
