While the criminal investigation surrounding Whitney Houston's daughter, Bobbi Kristina Brown, is underway, her boyfriend Nick Gordon has stepped out of the limelight and is doing well in rehab, according to a People magazine source.

"The best thing for Nick is that he is out of the way, out of the limelight," the source told the publication. "This way he can continue the process to improve himself and move forward in a better life. It is a blessing that he is in rehab."

Nick Gordon checked into rehab after Dr. Phil McGraw hosted an "emotionally charged" intervention last month on "The Dr. Phil Show," People magazine reports.

"Nick is responding well to rehab treatment with no relapses," the source continued. "The quiet time is good for him. He needed it."

Bobby Brown banned Nick Gordon, 25, from visiting his daughter, Bobbi Kristina Brown, in the hospital, where she remains in a medically-induced coma after she was found unresponsive in a bathtub on Jan. 31. The stress led Gordon to post numerous suicidal messages on Twitter before his intervention on "The Dr. Phil Show."

"Nick is a special person with many temptations and needs to be in a place where he can continue to heal and grow," the source told People magazine. "He should stay for a long time - as long as he will allow."

Meanwhile, in the latest development in Nick Gordon's investigation, Bobbi Kristina Brown's cousin, Jerod Brown, came forward with support for Nick Gordon, writing in a Facebook post that he is one of the reasons Whitney Houston's daughter is still alive today.

"For the record: Nick has cooperated with the police department," Jerod Brown wrote. "He has cooperated with my uncle Bobby's request, He has given my family members as much information as he can, he has been exploited on national television with hidden cameras that he had no idea about, He has given Kristina CPR which is one of the reasons why she is not dead till this day, he has been ridiculed and accused without any concrete evidence yet he still hasn't gotten the chance to visit his girl. If everyone truly believes that Nick is the blame for this situation wouldn't you think he would already be locked up by now ‪#‎Facts‬"

According to People magazine, last Sunday, Leolah claimed that Nick was under investigation for Bobbi Kristina's near drowning and that there was "strong evidence of foul play."
