To make matters even worse, Karrueche actually knows Chris baby mama, HollywoodLife.com has exclusively learned.

Theyre not besties or anything like that, but Karrueche knows who she is. Shes one of those girls who smiles in your face but will f**k your man behind your back, our insider revealed. But it aint even about the girl and Kaes not about to sit up here and put her on blast or dog her out.

Karrueche wasnt so shy about putting Chris on blast, however. She took to Twitter on March 4 to announce that she was done with him, saying, Listen. One can only take so much. The best of luck to Chris and his family. No baby drama for me.
