A young man who Whitney Houston reportedly considered as her unofficially adopted son could soon no longer be welcomed at the singer's Atlanta home if Cissy Houston gets her way. TMZ is reporting that Houston's mother believes he is a bad influence on Bobbi Kristina Brown.

TMZ is reporting that Cissy believes that Nick Gordon,22, who Whitney Houston treated like her own son, is a bad influence on Bobbi Kristina Brown. Bobbi Kristina is the only child for Whitney Houston and ex-husband Bobby Brown.

Family sources reportedly told the celebrity news Web site that Whitney Houston opened her home to Gordon more than 10 years ago. This was after the singer learned that Gordon's mother was no longer able to care for him as she should.  

Whitney Houston took in the boy and treated him like family up until Feb. 11, the day she died in a hotel bathtub in her suite at the Beverly Hilton in California.

But now, sources tell us ... Cissy Houston believes Nick is a bad influence on her granddaughter and wants him OUT of the Houston family home in Atlanta ... ASAP, the TMZ report reads. We're told Cissy has already informed her lawyers about the eviction ... in case he puts up a fight.

TMZ reports that it is unable to confirm whether Houston included Gordon on her will.
