And such is the life of celebrity DJs: Like the nightspots they spin at, their buzzworthiness has a short shelf life. Take DJ AM, who rocketed on the scene in 2003 when he was dating Nicole Richie. Since their split, he's entertained himself with celebrity trysts that include Mandy Moore, but without a starlet on his arm, his demand has plummeted. Gone are the five-figure fees from clubs in NYC, LA, the Hamptons, and international destinations; instead, corporate gigs, like this week's Palm Centro smartphone launch in out in Beverly Hills, are what's paying the bills. But AM, real name Adam Goldstein, isn't the outlier.

Should Lindsay Lohan graduate from her lesbian stage, it's likely Samantha Ronson, who can pull a rumored $25-50k per gig, will disappear from the paparazzi photos as well as event planners' must-have list. (Disclosure: Ronson has been hired by this blog owner's partner.)

Celebrity DJs, after all, are not always hired for their talents — there's a difference between Peter Rauhofer, who became a celebrity by himself, thanks to his club gigs and high-profile producing credits – but because their mere presence at an event draws media buzz. Without an actual celebrity commodity on their arm, these spinsters become, um, just that.
