Gospel star BeBe Winans, whose funny, emotional tribute during Whitney Houston's funeral was among the highlights of that moving service, remains in fervent prayer for the late singer's daughter, Bobbi Kristina Brown.

"Bobbi Kristina is my godchild, CeCe's goddaughter," he said during a recent interview with the AJC, referring to his sister CeCe Winans. "Whitney and us were very, very close. My children were Whitney's godchildren. It's very difficult."

Bobbi Kristina has been hospitalized since a Jan. 31 medical emergency. She recently was moved to a rehabilitation facility.

CeCe Winans has been visiting often, her brother said

"It’s family," BeBe said. "So we do all that we can, coming down  –  CeCe’s been down there constantly. And we’re just praying. That’s what we know to do. We believe in miracles and so it’s very, very difficult."

Here's a video clip of BeBe's heartfelt tribute during Whitney's funeral:

The thought of now saying goodbye to Bobbi Kristina is difficult, he said.

"It’s hard to even imagine, it really is," he said. "You know, Whitney, it’s someone like my brother Ronald who passed -- I think of her every day. And you just want the best for Bobbi Kristina, so we ask everyone to continue to pray that a miracle does happen, and that’s what we need."
