Bobbi Kristina Brown still in coma

Late singer Whitney Houston's daughter Bobbi Kristina Brown is still in a coma, after she was taken off some medications in a failed bid to bring her back to consciousness.

But the doctors had to put her back on the drugs once more because of seizures following the medication removal Wednesday..

"This is a horrible setback. Everyone was hopeful that this was the sign that she'd turned the corner. We were so optimistic," a source told people.com.

Although Bobbi Kristina's father, Bobby Brown was optimistic about the removal of medications, it turns out that all the family wants right now is for people to pray for the 21-year-old's recovery.

"Bobby is taking this so hard; he was sure this was going to be a good day. But please, everyone needs to pray for Krissi. I don't care what religion you are, or if you have no religion at all. Send your thoughts, your prayers, your well-wishes. Send everything you've got. Please," the source added.

Bobbi Kristina was placed in a medically-induced coma after being found unresponsive in a bathtub at her Atlanta home Jan 31.

Meanwhile, her beau Nick Gordon slammed Bobbi Kristina's family for continuing to block his attempts to visit her.

He tweeted: "My heart is full of anger after the Browns have shut me out. They don't even know her. Sabotage.

"I miss her so much. I seem so weak right now. You all have been so supportive! Thank you for everything," he added.
