Whitney Houston on Wednesday cancelled the first dates of her European comeback tour as the US pop diva underwent treatment for a respiratory infection at a Paris hospital.
The 46-year-old, whose hits in the 1980s and 1990s included "I Will Always Love You" and "I Wanna Dance With Somebody," had been scheduled to play a gig in Paris on Tuesday but cancelled it at the last moment. Another three performances in Britain were also postponed early on Wednesday.
"Doctors visited Whitney late last night in Paris and confirmed that she was suffering from an upper respiratory infection," he label Sony Music said in a statement to the media.
"Upon medical advice Whitney has been advised that she cannot perform to allow her time to recover," a statement from Sony Music said.
She was scheduled to perform in Manchester on Thursday and Friday, and in the Scottish city of Glasgow on Sunday, but the organisers said they too had been postponed.
Sony said she hoped to play a concert in Birmingham on April 13 before continuing the European tour.
French media reports said the star was being treated at the American Hospital in Neuilly, a clinic in a chic Paris suburb favoured by French celebrities. She was treated there in 2005 for gastroenteritis.
Doctor Francois Zuccarelli told AFP that the insurance company of the Paris-Bercy venue where she had been due to perform had asked him to visit her Tuesday in the Neuilly hospital to check on her health status.
"My problem was to find out if she were able to sing at Bercy. I certified that she was not able to sing," he said.
The health problems were yet another setback for Houston, whose career peaked in the 1990s, boosted by her acting appearance alongside Kevin Costner in the hit movie "Bodyguard".
She is attempting a comeback with the global "Nothing But Love" tour, which kicked off at the end of last year.
Houston has sold more than 170 million albums worldwide but suffered a major career setback after admitting drug use during an abusive relationship with ex-husband Bobby Brown.
After a seven-year absence from the stage and recording studios, the entertainer released a new album, "I Look to You", last year as part of her bid to regain past glory.
The album was well received by critics but the promotional tour has been plagued with problems. At a concert in Moscow in December she stumbled as she sang her signature tune, "I Will Always Love You."
In Australia in February, disappointed fans stormed out of her first concert in the country in 12 years after the ageing diva failed to hit her famous high notes and struggled for breath.
Houston only managed two songs before taking an extended break and relied heavily on backup singers, reviewers said, with some remarking she seemed disorientated and unable to remember the names of her band members.
After taking the world by storm in the 1980s, Houston later fell on relatively harder times with a drop-off in record sales, run-ins with the police over drug use and her divorce with Bobby Brown.
Brown was one of the hottest rhythm and blues singers in the late 1980s and early 90s, but became better known as the husband of Houston and for his frequent brushes with drugs and the law.
The pair, who were divorced in 2007, starred in a television reality series, "Being Bobby Brown," that featured their marriage, warts and all.
Brown was detained in Atlanta in 1993 for lewd conduct and for brawling in 1995. He was arrested for drunk driving in 1996 and for alleged battery of Houston in late 2003.
