Nick Gordon has slammed Bobby Brown's "baseless speculation" over Whitney Houston and Bobbi Kristina Brown's deaths.

Whitney died in 2012 aged 48 from accidental drowning, though drug use was a contributing factor in her ill-health, and her and her ex-husband's only child was also found unresponsive in her bathtub in January 2015, passing away almost six months later.

Speaking of their deaths on '20/20', Bobby said: "It's not a mystery to me the same thing that happened to my daughter is what happened to Whitney. There is only one person around both occasions.

"He knows what happened. I don't know what happened that night, but he does."

And now Nick's attorney, Jose Baez, has slammed Bobby - who split from Whitney in 2006 after 14 years of marriage - for his claims.

In an exclusive statement to People magazine, he said: "We have repeatedly said that Nick Gordon is innocent of any wrongdoing. He has not been charged with any crime. Enough is enough; let's end this baseless speculation."

Nick previously hit out at those who have blamed him for the deaths of Whitney and Bobbi.

He said: "Regardless of what everybody thinks, I made Krissy and Whitney's last few years on earth as happy as they would be.

"I gave them somebody to trust to, to talk to, to be there, someone genuine."

And he was especially scathing about Bobby, saying: "[Bobby] hurt his own daughter, not me. I was the one there for her while she was dealing with him not being there. He's not a reasonable person so I'm not planning on talking to him and I really don't want to."
