The incident occurred yesterday around lunchtime when police stopped Brown for talking on his cell phone while driving. Once they got closer to the star, however, it became clear he was under the influence of a substance. They gave him a sobriety test, which he failed. Brown was later released on bail.
Houston and Brown have famously battled substance abuse for years; at one point, Brown admitted to being addicted to cocaine, crack, and alcohol and is rumored to have been involved with heroin. In 2004, he told Dateline NBC that the drug use started for him after he married Houston, because his career took a back seat not only to her rising star, but to their marriage. Many of her fans, friends and family worried that Brown, who had a reputation for being a "bad boy", would hurt her career.
Brown has been touring with his old group New Edition for their 30th anniversary, but it is unclear just yet how the arrest will affect the scheduled performances.
