Bobbi Kristina Tells TMZ She Wants To change her name "because of its association with her father Bobby Brown."

She says she wanted to switch to Kristina Houston when her parents first split, in 2006, but her mother didn't allow it at the time.  MORE ON THAT TOPIC HERE

Now the 19-year-old is rushing to make the swap and is doing so with a "sober mind," according to the gossip blog.

In an interview that aired last night on OWN, Bobbi Kristina said it hurts too much to listen to her mother's music, but she can "still hear" the late singer's voice. She told Oprah, "Lights turn on and off, and I'm like, 'Mom, what are you doing?'"
