A source briefed on Whitney Houston’s behavior before her tragic death tells CNN that the singer was drinking heavily on two mornings last week. Houston reportedly ordered drinks before 10 a.m. on Wednesday and Thursday from the hotel’s bar and pool. The guests who saw this say Houston caused a ruckus, complaining that her beverages were “watered down” or stuffed with ice. The singer was also “disheveled” and wearing mismatched clothing. The source tells CNN that Houston jumped in and out of the pool—and did somersaults. While some of the drinking was done alone, she was also with an entourage and a male companion. On her final day, Saturday, she was seen drinking by the pool in the morning. Houston's funeral service this Saturday will be broadcast live, and jumbo screens will be set up outside the New Hope Baptist Church in Newark, N.J.
