Whitney Houston and Bobby Brown

After a crazy 14-year marriage marked by drug arrests and stints in rehab, Whitney Houston is divorcing Bobby Brown.

The move is hardly unexpected – Houston, 43, filed for legal separation from her husband of 14 years on Sept. 8.

Houston had asked in her separation papers that she be granted custody of the couple's 13-year-old daughter Bobbi Kristina, and that Brown, 37, be allowed visitation rights.

The couple wed in 1992, with Houston at the height of her fame as a Grammy-winning superstar known for such hits as "I Will Always Love You."

During their marriage, Brown was arrested for drugs and alcohol and Houston entered drug rehabilitation programs twice.
