American pop star Whitney Houston has filed for divorce from singer Bobby Brown, after 14 years of marriage.
Houston, 43, has won six Grammy awards and scored a string of chart-toppers, including Saving All My Love For You.
But her career has faded in recent years, amid stays in drug rehabilitation clinics.
Ms Houston has a 13-year-old daughter with Brown, whose own singing career has been overshadowed by brushes with police over drugs and alcohol.
Her publicist Nancy Seltzer confirmed that she had filed for divorce, but refused to say where or when.
She said the singer had no statement to make.
Drug abuse
Houston followed her mother Cissy Houston and cousin Dionne Warwick by beginning her vocal career in gospel and was topping the charts by 1985.
After a string of hits she pursued acting, appearing next to Kevin Costner in the hit film The Bodyguard.
She has not released an album since 2002.
Ms Houston admitted on US TV network ABC in 2002 that she had abused drugs but had overcome her problems through prayer.
She married Bobby Brown, 37, in 1992. Their daughter, Bobbi Kristina, was born the following year.
Mr Brown rose to fame as a member of New Edition, and in 1988 had a hit solo album, Don't Be Cruel.
