While Khloé Kardashian is busy taking care of her new bundle of joy True Thompson and dealing with the fallout of Tristan Thompson's cheating scandal, her baby daddy is still canoodling with one of his mistresses. A source tells In Touch exclusively on April 24 that Tristan is still very much in contact with Lani Blair, and he doesn't seem to have any plans to stop sexting and hooking up with her!

“Lani and Tristan are still talking," said the insider. "Still sexting. And are still hooking up! Only this time, it’s behind the scenes." A source had previously told us he was "desperately trying to win back Khloé's trust," but apparently two weeks was his cutoff and the groveling is done. "Tristan’s got a lot going on and needs his mental state to be on point," the source continued. "He just had a new baby. He’s in the playoffs. He’s trying to stay focused right now and it’s like Lani’s the only woman who gets him. She’s definitely being a calm, warm and loving person to him. Tristan needs that right now!" Well, we bet Khloé needs that right now too and guess what? She doesn't have it.

We bet Scott Disick feels stupid for feeling bad for Tristan now that it's clear that he doesn't care about Khloé at all. Even Lamar Odom, who also reportedly cheated on Khloé himself, thinks what Tristan did (and is continuing to do) is messed up, and he feels awful for his ex-wife. While Khloé certainly doesn't need Tristan's help in raising little True, we can't believe that he's still not even trying to be faithful to her weeks after she welcomed their first child.

To make matters worse, it definitely seems like Lani has no remorse for the pain she's causing either. As a matter of fact, it looks like she's been sending secret messages to Tristan on her Instagram for a while now. On one sexy selfie she wrote, "Every time I see you walking by I get a thrill… You don't notice me but in time you will. ?" And for another pic, she wrote: "Hey lady, let me tell you why. ?" Sketchy af, if you ask us.
