Bobby Brown’s sister Leolah was escorted from her niece Bobbi Kristina’s memorial service on Saturday after lashing out verbally at Pat Houston, former manager and sister-in-law to Bobbi Kristina’s mother Whitney Houston.

According to the Associated Press, Leolah Brown told reporters outside the church that she was angry over some of the things Houston said inside. “I told her that Whitney is going to haunt her from the grave,” Brown said, calling Pat Houston a “phony” and not a “blood relative.”

TMZ reports that security removed Brown from the church, and Tyler Perry helped calm the situation.

“It’s just getting started,” Brown told reporters. This is the latest skirmish in a long-standing feud between the families of Bobbi Kristina’s mother and father.

In January, Bobbi Kristina was found face-down and unresponsive in a bathtub in the Atlanta home she shared with Nick Gordon, whom her mother had adopted and raised, and who Bobbi Kristina called her husband. Police are investigating the incident as a drowing, the AP reports, and Leolah Brown said she believes Gordon was somehow involved.

According to Extra, Leolah Brown also implied that Pat Houston—who organized the memorial service on Saturday—may have had something to do with her niece’s death:

“... This was not something that just happens, okay? This is going to be connected. Okay, yes—I’m angry at Nick [Gordon], I’m angry at what happened to my niece, but Pat had something to do with it.”

Claiming to have “information, knowledge, and evidence” of “who Pat Houston is,” Brown promised she will continue speaking out and said she will give interviews on the subject.

On Friday, TMZ reported that invitations to the memorial service suggested that, in lieu of flowers, donations be sent to Pat Houston’s charity group The Marion P. Foundation.
