Landon Brown, son of Bobby Brown at Claudia Jordan's 35th Birthday Bash at Boulevard 3. Hollywood, California - 13.04.08

Landon Brown says Houston was a "nightmare" to grow up with, refusing to accept him as a member of her family.

He tells the National Enquirer that his former stepmum insisted he slept in a guest house when he came to stay - and refused to let him spend time with her daughter - his half-sister - Bobbi Kristina.

He says, "Whitney and I never really got along. She didn't necessarily hate me, but she wouldn't really speak to me either. In Whitney's eyes, I was the stepchild."

He adds, "She decided to turn me into one of her security personnel. I was a teenager but I was walking around dressed up in all black with a Security shirt and she'd have me work for her. I was just another one of her staff."
