Kenny Chesney: Broken Wiener or Wiener that just likes other Wieners

Renee Zellweger, who has filed for an annulment from husband Kenny Chesney after just four months of marriage, says the couple "hope to experience this transition as privately as

In court papers filed Wednesday in Los Angeles County Superior Court, the Oscar-winning actress listed "fraud" as the reason for the breakup with the country music star.
The term was "simply legal language and not a refection of Kenny's character," Zellweger said in a statement Friday. "I would personally be very grateful for your support in refraining from drawing derogatory, hurtful, sensationalized or untrue conclusions," she said. "We hope to experience this transition as privately as possible." (AP)
