Bobbi Kristina Brown’s funeral service Saturday was reportedly “perfect” despite minor hiccups due to an interruption by Bobby Brown's sister Leolah Brown, who had to be escorted out of the venue. Ellin LaVar, former hairstylist of Bobbi Kristina’s late mother Whitney Houston, told E! News details about the closed casket service at St. James United Methodist Church in Alpharetta, Georgia, for the 22-year-old.

LaVar said close family friend Tyler Perry had put together a movie compiling home videos of Bobbi Kristina from about the age of 1 until adulthood. "It was really touching video," LaVar reportedly said. "It ended like she was waving goodbye. It was very emotional to see it."

Three Grammy award winners -- Bobbi Kristina’s grandmother Cissy Houston, Donnie McClurkin and Cece Winans -- performed songs at the "simple and lovely" service, she added. The funeral was "perfect, like her, small and delicate," LaVar reportedly said. "The service was very low key and appropriate for her and her life."

However, things turned ugly when Leolah reportedly walked out in the middle of the service when Whitney's sister Pat Houston began speaking. Later, Leolah also allegedly made "inappropriate" comments on Pat.

"She got up during the service to show her anger and her niece went over to ask her to leave and calm her down. ... What she was doing was inappropriate," LaVar reportedly said, adding: "[Perry] went over there to keep the peace," and Leolah was "escorted out and asked to leave."

After making the exit, Leolah told news reporters: “Whitney will haunt Pat Houston from the grave. She will haunt her. Pat, it's not over. It has just begun. It has just begun. ... I say that because I have information, I have evidence, I have knowledge of who Pat really is, and she is not any relation whatsoever to Krissi. She’s not even a Houston, she’s a Garland. But Pat Houston has -- this is going to be a long, drawn-out thing. Trust me. It’s not over.

“It went wonderful until Pat started speaking, and I didn’t like that, so I left,” Leolah said, adding: “I just told her that Whitney was going to haunt her from the grave.”

Referring to Leolah's comments, Meeta Brown, Bobbi Kristina’s cousin, told TMZ: “I don’t know why she would do that in a beautiful homegoing and service for my sister. ... What I can tell you is that she’s [Leolah] crazy.”

Meeta, who was at Bobbi Kristina’s bedside several times in the last six months, however, said there was no “bad blood” between the Houstons and the Browns.

Leolah's latest comments come soon after she appealed to people to stop contributing to Pat’s charity, accusing the latter of trying to “get money put into her account for her personal gain.” Pat had urged the public to donate money to her foundation on behalf of her niece.

Bobbi Kristina died at the Peachtree Christina Hospice last Sunday after remaining in an unconscious state for nearly six months. She will be buried in New Jersey on Monday, next to her mother.
