Bobbi Kristina Brown's funeral was "simple and lovely"

She added: "The service was very low key and appropriate for her and her life. It was beautiful."

The service saw Tyler Perry, Bobbi's aunts Pat and Tina Houston, her best friends and middle school principal address the mourners, while her grandmother Cissy Houston, Donnie McClurkin and Cece Winans performed songs.

And in a touching tribute, Donnie sang 'Stand', the same song he performed at Whitney's funeral in 2012.

Family friend Tyler had put together a special film of home videos featuring Bobbi Kristina from the age of one to adulthood, and its airing was a particularly emotional part of the service.

Ellin told E! News: "It was really touching video. It ended like she was waving goodbye. It was very emotional to see it."

Despite praising the "perfect" service, there was an incident which saw Bobby Brown's sister Leolah asked to leave after she confronted Pat - a co-guardian of Bobbi Kristina's estate - when she got up to speak.

Ellin said: "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."

And family friend Tyler - who was recently said to be "keeping the peace" between the Brown and Houston families following Bobbi Kristina's death last week - was among several people who tried to calm Leolah down.

Ellin added: "He went over there to keep the peace. [Leolah] was escorted out and asked to leave."

Bobbi Kristina - whose body was placed in a silver casket adorned with roses - passed away on July 26, almost six months after she was found unresponsive in her bath.
