Khloe Kardashian isn't gonna let some jezebel slow her down ... she was back to work today taping KUWTK at their Calabasas studio. The newly-cropped bottle blonde carried a hot pink Hermes back and wore -- funny enough -- a Playboy hoodie with leggings.

Khloe must be feeling a bit sicker after listening to former friend Jordyn Woods' Red Table Talk interview by another family friend Jada Pinkett-Smith. The self-serving appearance saw Jordy saying she'd even take a lie detector test to "prove" she didn't sleep with Tristan but only that he gave her a kiss on the lips as she left his house the morning after a party he hosted. Uh, yeah ...

Woods also said there have been death threats against her family -- which IS crazy. She says that's the reason she wanted to speak out and set the record straight.

Well Khloe called the whole thing "lies" and blames Jordyn for breaking up her family. Now frankly, Khloe's overdoing it a little -- Tristan is a BIG TIME dirty dog and if he hadn't been with Jordyn, it would have been (and probably had already been) with someone else anyway. Poor girl just can't catch a break, though!
