Perry, 45, has remained in contact with the Brown and Houston families in the months following the Jan. 31 incident that left the 22-year-old incapacitated.
The Gone Girl star has long been close with the family, especially Bobbi Kristina’s mother, the late Whitney Houston.
The star also worked with Bobbi Kristina when she made a 2012 guest appearance on his TBS series For Better or Worse.
He first visited Bobbi Kristina during her stay at Emory University Hospital in February.

Perry reportedly also gave her father, Bobby Brown, a lift on his private jet to see his ailing daughter around the same time, and has been helping the family ever since, according to his close friend Oprah Winfrey.
Other hospice visitors over the weekend have included Bobbi Kristina’s aunt Pat Houston, who serves as her legal joint-guardian, and Bobby’s sisters Tina and Leolah Brown.
The review was in response to a claim filed by Bobbi Kristina’s court-appointed conservatory alleging her boyfriend Nick Gordon caused “substantial bodily harm” and stole $11,000 from the star.
A close relative of Gordon previously told PEOPLE that they felt that he was being used as “a scapegoat” in the incident.
