Actor Larry Hagman has died at age 81.  Hagman passed away with family and close friends by his side last Friday.  His co-star Linda Gray was with Larry in his final moments and remembers her "best friend" fondly.  Larry rocketed to fame as Major Tony Nelson on the 60s NBC TV series I Dream of Jeannie.  But it was his role as TV villain J.R. Ewing for which he'll be most remembered.  Larry made several appearances on the TNT Dallas re-boot earlier this year.  It's not known how the series will address Hagman's death when its second season begins in January.
