Jessica Simpson is tired of dating jocks and musicians - she's ready for an academic. The singer has endured a string of failed relationships since the breakdown of her marriage to singer Nick Lachey in 2005, including rocker John Mayer and football "star" Tony Romo.

And Simpson has revealed why she is still single - she gets bored easily and craves intellectual stimulation.

She tells Extra, "I don't want to get bored. I can bore out pretty easily, so I love intellectual men - people that will always keep me intrigued."
