Bobbi Kristina Visits Mom's Grave on 'Houstons'

In a new clip of Lifetime's upcoming reality series, The Houstons: On Our Own, we see how big a role Bobbi Kristina's family has played in comforting her during the holidays.

As Whitney Houston passed in February, this year marked Bobbi Kristina's first Mother's Day without her mom. Fortunately, Bobbi's aunt, Patricia Houston, was by her side.

"She would be very, very proud of you right now," Pat tells Bobbi before heading off to visit Whitney's gravesite.

"At this point in time, I'm completely terrified but I'm going," Bobbi admits to the camera in a one-on-one session. "I'm praying to God that I can get out of this car. I'm praying to God that he gives me strength to keep walking towards her grave."

The Houstons: On Our Own premieres Wednesday on Lifetime.
