"Whitney was a little bit of a party girl. She loved it, she was good at it," said singer Natalie Cole.
Cole is remarkably candid about her friend, the late Whitney Houston.
"She knew exactly what she was doing. I don't think she meant to leave here. And once the toxicology report came in, I wasn't surprised. Everyone wanted to believe that after at least two rehabs, that she was coming along. But the demons were still chasing her," said Cole.
On Piers Morgan's CNN show, Cole also said it was unfair to blame Houston's ex, Bobby Brown, for Houston's downfall.
Bobby Brown's sister, Leolah, told INSIDE EDITION's Lisa Guerrero the same thing when she sat down with her in an exclusive interview.
"A lot of people will blame your brother for Whitney Houston turning to drugs. How would you respond to that?" asked Guerrero.
"People don't know Bobby. They don't, and I think people just use Bobby as a convenient vehicle, because it worked for them at the time. But Bobby has nothing to do with Whitney being on drugs. Whitney has other people in her family that have introduced her to drugs, way before Bobby came in the picture" said Leolah.
But Brown may still be dealing with his own substance-abuse issues. Cops busted him on Monday on a DUI charge.
Cops say Brown was pulled over at an intersection in Los Angeles Monday for talking on a cell phone while driving. They say he appeared to be impaired, and failed a field sobriety test. He was booked on suspicion of DUI.
Monday night, Houston's cousin, Dionne Warwick, and mentor Clive Davis made their first public appearance since the star's funeral.
Warwick was being honored at the Grammy Museum in Los Angeles. She refused to answer questions about Houston.
"That is something I told you I did not want to talk about," said Warwick.
