Tigers don't change their stripes!

Khloe Kardashian has reason to believe baby daddy Tristan Thompson is still cheating on her, and she's in total panic mode over how to address the situation and get to the bottom of it, Radar reports.

"She thinks it’s possible he’s still cheating. He leaves her and True at the house late, telling Khloe he’s going to the Cavs training facility to practice. He comes back, hours later, smelling all sexy and clean and has no energy," a source dished to the outlet.

"She’s freaking out. She wants to confront him about it but doesn’t want to come off as insecure and put more stress on him in the finals. He has all the chances and opportunities to cheat and she can’t handle it," the source added.

The Revenge Body star is terrified to bring up her concerns, because the athlete manipulates her into thinking she's paranoid. Not only that, but TT knows he's in the position of power and is using that to his advantage.

"Tristan continues to insist he’s done nothing wrong, and blames Khloe’s family for exaggerating his womanizing and trying to ruin his reputation. He’s willing to walk away, but Khloe’s desperate to work this out, so Tristan’s in the driver's seat," the insider revealed.

She should quit dragging this out and just dump this loser already!
