Who was with Whitney Houston on the tragic day she was found dead in the bathtub of her Beverly Hilton Hotel room?

The fallen star, whose official cause of death was ruled as "drowning and effects of atherosclerotic heart disease and cocaine use" was scheduled to shoot an infomercial before attending Clive Davis' party that night and had an entourage of family, security, assistants and makeup artists around her.

Whitney's daughter, 19-year-old Bobbi Kristina, said she spent the entire night before with her mom, telling Oprah: "I went to go get her and I said, 'Come lay with me.' She stayed with me all night and all day. She was just rubbing my head and holding me. I just slept in her arms."

But on February 11, the day of Whitney's death, her sister-in-law Patricia Houston said she had not yet had face time with the I Will Always Love You singer and didn't walk into her hotel room until it was already too late.

Whitney's assistant, Mary, was the first to find Whitney's unresponsive body in the bathtub and then her security guard, Ray, attempted CPR to the point of exhaustion before medical personnel arrived — two minutes after a 911 call was placed at 3:43 p.m.

Despite reports, Ray J, who was rumored to have been dating Whitney at the time, was nowhere near the hotel at the time of her death.

Houston's cousin and close friend, Dionne Warwick, is one of the last known people to speak to Whitney alive, telling Good Morning America, "I spoke to her the morning of her death. She said, ‘You’re here, aren’t you? You’re coming to the party, aren’t you?’ I said, ‘Yeah, I’m going to be there’ and she said, ‘Thank you, I want you to be here. You’ve got to be here for me.’”
