Things are getting nasty between R&B singer Bobby Brown and Nick Gordon. There have been reports that the two have been feuding because Bobby banned Gordon from visiting Bobbi Kristina Brown at the hospital.

The 21-year-old daughter of Bobby and the late Whitney Houston has been in a medically induced coma for three weeks after she was found face down in a filled bathtub at her Georgia home on Jan. 31.

According to TMZ, Bobby has agreed to let Gordon visit his comatose girlfriend only if he talks to the police about what happened the morning Bobbi Kristina was found unresponsive. A lawyer for the New Edition frontman said that Gordon refused to meet the terms of the agreement and therefore could not step foot inside Emory Hospital to see Bobbi Kristina.

"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," lawyer Chris Brown said. "Mr. Gordon has every right to remain silent and not share his version of events with Bobby Brown... Mr. Gordon is not as desperate to visit Bobbi Kristina as he wants to the world to believe."

On Monday, Gordon launched an attack against Bobby tweeting a screen grab of supposed text messages he sent to the singer asking for visitation.

"Man to man I love your daughter. I don't know why you won't let me see her," he says in some of the messages. "Grow up... It's not like you know her anyways. What's her favorite color? What's her favorite smell, movie, food. You don't know. I forgive you she won't."

He also said that if Bobby could "guarantee me that I can see her 24/7 I'll meet the conditions."

"I can't wait till she wakes up and dismiss all of the negative thoughts. There is a reason why her mom made me promise to look after her," Gordon wrote on Sunday.

It's been reported that Gordon was being investigated by police after doctors allegedly discovered mysterious bruises around Bobbi Kristina's mouth.
