Bobbi Kristina and Whitney Houston's "adopted" son, Nick Gordon, recently took their fling public and were spotted holding hands and kissing during a lunch date in Atlanta. There has even been speculation of a secret engagement after photos surfaced of a large diamond ring on Bobbi's left hand.

Cissy Houston, Whitney's mother, is flipping out over the couple's budding romance, calling it incestuous. According to TMZ, Cissy is worried about Bobbi Kristina and believes Nick Gordon might be taking advantage of her granddaughter despite the fact that the two have been very close for many years. They even considered each other brother and sister at a time.

Nonetheless, Cissy is desperately trying to protect Bobbi Kristina's inheritance and is even asking the Whitney Houston Estate to legally evict Gordon from Whitney's Atlanta mansion, where Bobbi Kristina lives. 

Things are bound to get ugly when incest accusations are flying around. Run for cover.
