Usher was in no mood to celebrate the conviction of the man who killed his stepson when he arrived Thursday at LAX.
Jeffrey Hubbard was just convicted of homicide for recklessly jet skiing. 11-year-old Kile Glover was riding an inner tube when he was struck by the jet ski and killed. Usher, who was married to Tameka, lived with the boy for several years and considered him his stepson.
Usher -- who has been in a nasty, ongoing legal fight with Tameka -- had words of sympathy for her and Kile's biological dad.
