Less than a month after sharing dinner together at Joe’s Crab Shack, cracked-out exes Bobby Brown and Whitney Houston are battling over teen daughter Bobbi Kristina.

In court papers filed earlier this week, Bobby says:

“Since Whitney has been awarded sole legal and physical custody of Bobbi Kris, she has attempted to eliminate me from Bobbi Kris’ life.” Brown claims he went out of his way to look after his estranged wife and their daughter when Houston was undergoing rehab for a drug abuse problem in 2006, but feels the singer is being far from generous when it comes to the time he spends with the teen.

He adds, “I did all I could to see my daughter. I also paid approximately $10,000 for Whitney and Bobby Kris to live in a nice hotel while Whitney was going through rehab. I basically lived in my car. I have not seen or spoken to my daughter since early June and I have no prospect of speaking to her or seeing her anytime soon due to Whitney’s actions.”

Whitney has responded with:

“We have a daughter together and I would like him to be involved in her life.” …..did not talk to him about reconciliation or marriage counseling. Frankly, I needed to be divorced from him so that I could get my life back on track.”
