ATLANTA (AP) -- The daughter of late singer and entertainer Whitney Houston was found unresponsive in a bathtub Saturday and taken to a hospital in the north Atlanta suburbs, police said.<br /> <br /> Bobbi Kristina Brown was found by her husband, Nick Gordon, and a friend and given CPR, said Officer Lisa Holland, a spokeswoman for the Roswell Police Department.

A representative for the family did not immediately return messages seeking comment.<br /> <br /> Whitney Houston was found dead in a hotel bathtub on Feb. 11, 2012, in Beverly Hills, California. The 48-year-old Houston had struggled for years with cocaine, marijuana and pills, and her behavior had become erratic.<br /> <br /> Authorities examining Houston's death found a dozen prescription drug bottles in the hotel suite. They concluded that Houston accidentally drowned. Heart disease and cocaine use were listed as contributing factors in Houston's death.<br /> <br /> Over her career, Houston sold more than 50 million records in the United States alone. Her voice, an ideal blend of power, grace and beauty, made classics out of songs like "Saving All My Love For You," "I Will Always Love You," "The Greatest Love of All" and "I'm Every Woman." Her six Grammys were only a fraction of her many awards.<br /> <br /> Houston had her first No. 1 hit by the time she was 22, followed by a flurry of No. 1 songs and multiplatinum records.<br /> <br /> Houston left her entire estate to her daughter.
