Tennis ace Serena Williams was in Toronto completing work on an episode of the Showtime drama Street Time over the weekend when news broke that her older sister Yetunde Price had been shot to death. The aspiring thesp immediately flew to Los Angeles to grieve with her family, leaving the fate of the Oct. 22 installment up in the air. Incidentally, Serena's Street Time gig is turning into a cursed production. Producers already delayed the episode's shoot from early August after Serena tore a tendon in her knee.
