TYLER PERRY: BOBBI KRISTINA DID NOT WALK OFF SET

Tyler Perry denies reports that Whitney Houston's daughter Bobbi Kristina walked off the set of his TV show For Better or Worse.

Bobbi Kristina has a small recurring role on the series, but there have been reports that she quit before the season ended, storming off the set in tears.

Tyler, who created the show, writes on his website that "there is no way that she could have walked off the set because we have finished taping the season."

He adds, "Were there tough days for her? Yes of course. Not because of the acting or any job-related issues but because of the fact that she had just lost her mother. So yes she was grieving, but grief aside, she managed to finish her obligation and did a great job at the same time."
