Los Angeles, March 17 (Reuters): Pop star Whitney Houston has entered a drug rehabilitation programme in an undisclosed location, her publicist has said.

The Grammy winning singer and actress, who is married to singer Bobby Brown, “thanks everyone for their support and prayers”, publicist Nancy Seltzer said. The couple, married since 1992, has a daughter, Bobbi Kristina, who was born in 1993.

Seltzer would not disclose what facility Houston had chosen or how long she is expected to be under treatment.
