American singer and actress Whitney Houston has died in Los Angeles at the age of 48.

The 48-year-old was best known for powerful ballads such as I Will Always Love You and One Moment In Time.

But her later career was overshadowed by substance abuse and her turbulent marriage to singer Bobby Brown.

The BBC's David Willis say some people believed she was making a comeback, but there had been reports she may have "slipped back into old habits".

Recent footage, courtesy of TMZ, showed her leaving a restaurant with singer Ray J.
