Whitney Houston has tagged reports claiming she will return to rehab as "ridiculous".

U.S. tabloid the National Enquirer had alleged that the singer had collapsed backstage and had been recommended to return to a rehabilitation centre.

However, the R and B star's attorney Marty Singer has refuted the report.

"Whitney is not headed to rehab. She is headed to Paris, where she will be continuing her world tour," the Daily Express quoted Singer as telling UsMagazine.com.

He added: "Ridiculous. It did not happen."

Houston has faced difficulty performing in her 'Nothing But Love' tour due to breathing problems caused by smoking.

She had admitted in an interview with Oprah Winfrey last year that she took drugs with former husband Bobby Brown. (ANI)
