Bobby Brown and his former sister-in-law Pat Houston are said to be bumping heads just after his daughter Bobbi Kristina Brown was released from the hospital and placed in a rehabilitation treatment center.

Bobbi Kristina Brown Out Of Hospital, Father Bobby 'Thought She'd Be Better By Now'

Word is Bobbi Kristina, whose parents are Bobby and the late Whitney Houston, is still in a coma nearly two months after she was discovered unresponsive in her bathtub. New reports say that Pat, who is Bobbi Kristina's aunt through marriage, hasn't made it easier on Bobby as he tries to cope with her current state.

Apparently Bobby runs the show and Pat is reportedly not happy about it.

"You can't tell Bobby what to do, and he is in charge. We are just letting him do what he wants. Pat is the only one who is standing up to Bobby and they're not happy with each other," an insider told People Saturday.

Still, a separate source said Pat and Bobby are getting along just fine.

"Bobby is the decision maker. Pat has been by Bobbi Kristina's side this whole time and is not butting heads with Bobby. Pat will support any decisions that Bobby makes about his daughter."

One of the decisions Bobby has said to make was to keep her in the hospital long after the family thought she should have been released to the rehab facility. But the first insider said it took weeks for them to get over the "shock" of what happened to Bobbi.

"Like, 'Oh my God, I can't believe that this happened.' But now we've had a lot of time to get used to it."
