Chris' now ex-GF just reacted to the story TMZ broke -- that Chris has a 9-month-old baby girl -- tweeting, "Listen. One can only take so much. The best of luck to Chris and his family."
As we reported ... the baby's mother is a 31-year-old woman named Nia ... who's been friends with Chris for several years.
Karrueche ended her tweet with a very definitive ... "No baby drama for me."
BTW -- props to KT for the brown baby avatar.
