Khloe Kardashian and Tristan Thompson's relationship is in shambles ... despite an appearance Khloe created that her union is still tight.
Sources familiar with the situation tell TMZ ... Khloe has not spoken to Tristan for several days because she's still furious after finding out he repeatedly cheated on her, and embarrassed her in the process.
We're told while Khloe's recent post made it appear as if she and Tristan were solid -- unveiling the baby's name as "our little girl," True Thompson -- sources tell us it's just a facade and their relationship is hanging by a thread.
