After a fling with Paris Hilton two years ago, Chicago Bears linebacker Brian Urlacher is tackling another Las Vegas-related scandal.
The Chicago Tribune reported last week that Urlacher is admitting in court papers that he fathered a child with a Chicago-area woman who claimed she was raped in Las Vegas in 2002 by Irish dance troupe star Michael Flatley.
Urlacher, in court papers seeking a ruling on child support, acknowledges that he and Tyna Robertson are the parents of a child born May 20. The paternity case was filed in Will County, Ill.
