Mariah Carey Drags Demi Lovato Into Jennifer Lopez Feud (VIDEO)

Mariah Carey finally responded to Demi Lovato's comments regarding Mariah's bad treatment of Jennifer Lopez through the years.

Mariah always says that she "doesn't know" JLo - even if she does and actually admitted she knew Jennifer early in her career. When JLo ascended into pop superstardom of course, things changed.

Mariah was on Bravo's Watch What Happens Live and did not hold back on what she thought of Demi Lovato. My god, this is a grown woman. Demi could be her granddaughter!
