Whitney Houston’s daughter Bobbi Kristina Brown and the late singer’s mother, Cissy Houston, haven’t been on the best terms lately.

Ever since Houston’s book “Remembering Whitney” was published in January, Brown has been keeping her distance from her grandmother, calling the book (which details Whitney’s drug abuse, problems with ex-husband Bobby Brown and gay relationship rumors) “disrespectful.”

Now, Houston is trying to mend fences, though in a very public way. She released an open letter to the press on last Wednesday, addressed to “Krissi,” and addressed the 20-year-old’s engagement to Nick Gordon.
