Bobbi Kristina Brown Condition, Health Latest News: Nick Gordon Fights With Father Bobby Brown

While the daughter of the late Whitney Houston fights for her life in the hospital, Bobbi Kristina's boyfriend has picked up a new fight against her father, Bobby Brown.

Nick Gordon posted another slew of rants, telling Brown to grow up on Twitter, a few hours after lawyers banned him from visiting the bedside of his comatose girlfriend.

In a series of posts on his Twitter account, Gordon claimed Brown failed to see his 21-year-old daughter for several years before she was found unresponsive face down in a bathtub last Jan. 31 in her Georgia home.

"Bobby seen his daughter 4 times in the last 5 years," Gordon said, according to the Daily Mail before adding: "Now him and his family want Whitneys $$$ which belongs to Krissi or Cissy."

Insisting he has taken care of Bobbi Kristina since her mother died in 2012, Gordon uploaded a screenshot of damning text messages he claimed to have sent Brown.

Gordon first tweeted: "Okay, so I'll probably get in trouble for this" before uploading a photo of a new Bobbi Kristina tattoo on his right arm that read: "Man to man I love your daughter."

"I don't know why you won't let me see her," he added before posting: "Grow up. Your daughter is going to hate you when she wakes up," according to the Daily Mail.

This came after a lawyer for Bobbi Kristina's father, Bobby Brown, said Gordon was offered an opportunity to potentially visit her if he agreed to meet certain conditions in a statement last Saturday.

But Gordon's attorneys said Sunday that Brown has consistently denied Gordon permission to visit, claiming they advised Gordon to refuse the conditions set by Brown.

"Those offers have also been rejected... We hope Mr. Brown has a change of heart," said Gordon's lawyers, Randy Kessler and Joe Habachy, in a Sunday statement, according to Billboard.

Houston brought Gordon into her household as an orphan at the age of 12, raising him and her daughter after divorcing Bobby Brown in 2007.

Relations between Gordon and some other family members soured last year: He remains subject to a protective order barring him from being within 200 feet of Bobbi Kristina's aunt, Patricia Houston.

Bobbi Kristina became the sole inheritor of her mother's estate when she died in 2012, and shortly thereafter, she and Gordon went public with their romantic relationship.

But Brown said his daughter isn't and never has been married to Gordon.

On Thursday, doctors replaced Bobbi Kristina's breathing tube with a tracheotomy tube, according to a person close to the family who was not authorized to speak on her condition.

The tracheotomy is usually used for patients who need to be on a ventilator for an extended period.
