The visit comes after Houston released a statement confirming her niece's condition continues "to deteriorate"
Pat, who is married to Whitney Houston‘s brother Gary and has been a constant by Bobbi Kristina’s side, and Bobby looked somber as they separately entered the Georgia facility Thursday with other family members.
On Wednesday, Houston – who was with Bobbi Kristina during her transfer to hospice care – released a statement on behalf of the Houston family revealing Bobbi Kristina’s condition has worsened.
“Despite the great medical care at numerous facilities, [her] condition has continued to deteriorate,” she said in the statement. “As of today, she has been moved into hospice care. We thank everyone for their support and prayers. She is in God’s hands now.”

Despite the grim news, her family continues to pray for a “miracle.”
“She is still alive and her heart is beating so there’s hope,” a Brown family source told PEOPLE. “God can perform a miracle.”

The 22-year-old was hospitalized in January after being found unconscious and unresponsive in a bathtub in her Atlanta townhouse. Still unresponsive after months in the hospital, Bobbi Kristina was transferred to an Atlanta-area rehab facility in March before being moved to hospice Wednesday.
A family source tells PEOPLE, “The heartbreak and pain we feel in seeing her that way is beyond words.”
