Whitney Houston: I wore PJs for seven months in drug hell

Whitney Houston says she spent seven months wearing just pyjamas in the depths of her drug hell with husband Bobby Brown.

Opening up: Whitney Houston reveals how her life spiraled out of control

In an exclusive two-part interview with Oprah Winfrey, Houston reveals how her life first began to spiral out of control after her hit film The Bodyguard in 1992. "It will leave you gasping," teased Winfrey. The episode is set to air in the US on Monday.

The chat show host added: "She does not blame Bobby Brown and she takes full responsibility for her engagement in drugs.

"At one point she says, I didn't get out of my pyjamas for seven months'." Winfrey said she asked the singer before the interview what she wanted to achieve "She said, I want to tell my story, I want to tell the truth'."

In her last television interview, in 2002 with Diane Sawyer, Houston famously denied taking crack cocaine. She told Sawyer at the time: "I make too much money to smoke crack. Crack is whack."
