(Cover) - EN Showbiz - Bobby Brown is apparently frustrated that he has not seen his daughter since his ex-wife Whitney Houston died.

Bobbi Kristina Brown is the singer's only child with Whitney who tragically passed away on Saturday afternoon.

TMZ reports that Bobby believes Whitney's mother Cissy Houston and the rest of the family are making it difficult for him to connect with the 18-year-old.

Sources told the site that since Bobby arrived back in Los Angeles on Sunday night he has not seen or spoken to Bobbi Kristina.

He apparently tried making several calls and attempted to see her to no avail. Bobbi is being cared for by Whitney's family and friend at a home in Los Angeles.

She has been rushed to hospital twice since finding out that her mother had died and is understandably distraught.

The My Prerogative star believes that Whitney's mother Cissy is putting the road blocks up against him because she has hated him for years.

Whitney and Bobby had a tumultuous 14-year marriage which officially ended in 2007 and he has been blamed by many for her drug abuse and fall from grace.

The I Will Always Love You icon will be laid to rest in a private memorial on Saturday in her home town in New Jersey. Bobby is said to be "extremely disappointed" on learning that Whitney's family do not want him to attend.

The 48-year-old was found dead in the bathroom of the Beverly Hilton hotel on Saturday sending shockwaves around the world. (C) Cover Media
