Nick Gordon has reportedly begged Bobby Brown for an invite to Bobbi Kristina Brown's funeral in an emotional e-mail.
Whitney Houston's daughter died on Sunday after six months in a coma and her boyfriend Gordon has been declared 'a person of interest' by police since her death.
He is alleged to have tried to buy drugs for the troubled 22-year-old on the day she was found unresponsive in her bathtub at her home in January.
