(CNN) -- Pop superstar Whitney Houston was seen ordering and consuming considerable quantities of alcohol at The Beverly Hilton two mornings last week, said a source briefed on her behavior and activity in the days before her death Saturday.

The source told CNN's Don Lemon that Houston ordered the drinks before 10 a.m. last Wednesday and Thursday from the lobby bar and in the pool area.

Guests both days overheard Houston loudly complaining about her drinks, accusing bartenders of "watering down" or "putting too much ice" in them, the source said Wednesday.

The source says other guests expressed concern about Houston's erratic behavior. Her disheveled appearance, including mismatched clothing, suggested to them that she was intoxicated, the source said. The source said Houston was seen jumping in and out of the pool and doing somersaults in the pool area.

Saturday's funeral for legendary pop singer Whitney Houston is expected to be made available for television and web streaming from the New Jersey church where she grew up, Houston's publicist said Wednesday.
