Martin D. Singer, 57

Entertainment litigation

Call Singer whatever you want — pit bull, Rottweiler, mad dog, whatever. But chances are you’ll be calling the aggressive defamation specialist your best friend, at least, if you’re a celebrity featured in the latest publicly released sex tape, nude photo, juicy tabloid scoop, or pretty much anything else that gives you a little too much “exposure.” Actors Eric Dane and Rebecca Gayheart learned that the hard way, when they recently hired Singer to rein in copies of the infamous video recording of the couple cavorting with another woman. But it’s not all salaciousness for Singer, who in the past year has gone into other kinds of legal battles for dozens of Hollywood elite, like Eddie Murphy, John Travolta, Bruce Willis, Sharon Stone and Charlie Sheen.
