Last week, the Kardashians. Tonight, Adrian Grenier. Coming in November: Joe Jonas.

90210 appears to be resorting to a few examples of stunt casting, the latest being the announcement that one-third of The Jonas Brothers will portray himself in an episode later this fall.

As first reported by Entertainment Weekly, Jonas will escort Adrianna to a magazine party and offer the aspiring musician some advice on the installment. It makes one wonder: Why isn't Navid Adrianna's date?

Sound off now: what do you think of this influx of famous guest stars? Do they distract from the storylines? Or add to your interest?
