I found a story about Kate Beckinsale and her husband, Len Wiseman, they have pulled the plug on their marriage ... TMZ has learned. Wiseman cited irreconcilable differences. His docs state both he and Kate have waived any right to spousal support, and that suggests there's a prenup. They were married in 2004 and have no kids together. TMZ broke the story ... the couple's marriage was on the rocks last November. Len was spotted out with model CJ Franco, and Kate we seen shortly after -- sans wedding ring -- on the red carpet.
