Bobbi Kristina Brown has reportedly been comatose since January 31 after being found unresponsive in a bathtub.

The 21-year-old’s boyfriend Nick Gordon has reportedly been barred by Bobbi Kristina’s father, Bobby Brown, from visiting the aspiring singer, which has resulted in the escalating tension between Gordon and his girlfriend’s family.

Gordon took to Twitter recently to express his frustration.

Bobby Brown reportedly told Nick Gordon that he couldn’t visit her in the hospital until he explains what happened the day his daughter was found, according to NBC News.

"Obviously Mr. Gordon is not as desperate to visit Bobbi Kristina as he wants the world to believe. At least not desperate enough to inform Bobby Brown, in writing, what happened to Bobbi Kristina," Christopher Brown, one of Bobby Brown's attorneys, told E! in a statement.

Gordon’s lawyers had reportedly said in a statement that they had advised the 25-year-old not to meet the conditions that Bobby Brown had laid out. Bobby Brown has reportedly continued to fire back on Gordon’s claims that he’s been “prohibited” from visiting Bobbi Kristina.

"Due to Mr. Gordon's failure to place in tangible form his understanding of the events that lead to the hospitalization of Bobbi Kristina, there is no reason for any additional discussion with him," Bobby's lawyer Christopher Brown said in the statement.

It continued, “It appears that Mr. Gordon did not want his understanding of the facts to be subject to the truthful examination of various experts or Bobby Brown himself. Mr. Gordon has every right to remain silent and not share his version of the events with Bobby Brown. We are only concerned with individuals that can help Bobbi Kristina and bring resolution to this investigation.”
