Brown arrived as the service began. He walked to the casket, touched it and walked to the back of the New Jersey church Saturday.
In a statement put out by his representative, he explained, "My children and I were invited to the funeral of my ex-wife Whitney Houston. We were seated by security and then subsequently asked to move on three separate occasions."
He continued, "I fail to understand why security treated my family this way and continue to ask us and no one else to move. Security then prevented me from attempting to see my daughter Bobbi-Kristina. In light of the events, I gave a kiss to the casket of my ex-wife and departed as I refused to create a scene. My children are completely distraught over the events. This was a day to honor Whitney. I doubt Whitney would have wanted this to occur." I will continue to pay my respects to my ex-wife the best way I know how."
Houston died Feb. 11. A cause of death hasn't been determined.
Houston and Brown were married 15 years and have one daughter. In 2003, police responding to a domestic violence call about Brown found Houston with a cut lip and bruised cheek. Their tumultuous relationship ended in 2007.
