Bobby Brown is "extremely disappointed" after hearing that several members of Whitney Houston's family do not want him to attend the singer's funeral ... sources tell TMZ.
Sources close to Bobby tell us ... people connected to the Houston family have reached out to Bobby to warn him that he shouldn't attempt to attend the funeral because the family isn't fond of him.
However ... we're told Bobby has not received any OFFICIAL word from the family about his invite status.
Sources tell us ... Bobby WANTS to attend the funeral so he can support his daughter Bobbi Kristina, but he hasn't decided on a plan of action yet.
Bottom line -- we're told Bobby is hoping the family will be able to set aside their differences so they all can focus on mourning the loss of their loved one.
