Bobby Brown is suing his ex-wife, Whitney Houston, in a bid to change his terms of custody with their teenage daughter. In court papers, the My Prerogative singer reveals he was too "strapped for cash" when his wife first filed for divorce last year (06) and couldn't afford to hire a lawyer to help him fight for custody. Brown says he's devastated about losing his rights to see his 14-year-old daughter Bobbi Kristina. The desperate singer admits he has been homeless at times since the divorce, and is seeking spousal support, as well as child support for their daughter. A court date for Brown's new case has set for 15 June (07). The couple's divorce was finalised last month (24Apr07).
