width=293Whitney Houston's barely cold, and her mother Cissy is already accusing her daughter Bobbi Kristina of incest!

At least, that's what gossip site TMZ is saying.

Rumors have been flying that Whitney's only biological daughter, Bobbi Kristina, is in a relationship with Nick Gordon, who was unofficially adopted into the family by Whitney about ten years ago and raise like a brother to Bobbi Kristina. Gordon half-heartedly denied that they were more than just friends to ABC, but video taken of the couple says otherwise.

Now Cissy Houston, Whitney's mother and Bobbi Kristina's grandmother, is weighing in. What they're doing is incestuous, Cissy reportedly told a close friend. TMZ also wrote that Cissy feels her granddaughter has problems and Nick is taking advantage of her.

This is not the first time Cissy has spoken out against the two. Shortly after Whitney's death, despite claims that Bobbi Kristina would be living with her family, Cissy was apparently pursuing legal action to have Nick Gordon evicted from the family home in Atlanta, where Whitney's children are both staying.

But that clearly didn't work, as the two are still living together – and, according to the evidence available, happily – in the Atlanta home. Bobbi Kristina said that she just wanted to be alone with her brudder on her birthday, and apparently she's wanted to remain with him since then.

Bobbi Kristina indirectly addressed the incest talk earlier in a tweet – or, actually, a retweet:
