AceShowbiz - It looks like the cheating scandal won't stop Tristan Thompson from hanging out with his alleged side chick Lani Blair. Words are, the basketball player invited the Instagram model to his playoffs after Khloe Kardashian handed him back her tickets.

"Khloe told him she isn't going to any of his playoff games in Cleveland and gave him back his four box seat tickets," a source told InTouch Weekly. "So Tristan gave the tickets to his sidepiece Lani!" The insider went on explaining that Tristan wasn't even hiding his feelings for Lani, saying, "He's crazy, crazy about Lani and isn't trying to hide her."

"Lani's been asking to come to his games to cheer him on for the longest time but Tristan always wanted to keep her in the background, until now," the source continued. His baby mama allegedly "has no idea that Tristan did this and it seems like Tristan doesn't care about her knowing either."

Tristan and Lani were first spotted together at PH-D Lounge on Saturday night, April 7. The latter was caught on camera draping her arms around Tristan's shoulder, pulling him closer. The athlete later was seen leaning for a kiss as he spoke with her.

Shortly after that, they were caught entering Tristan's hotel, the Four Seasons, at 5 A.M. At that time, onlookers said that Tristan was seen "looking around cautiously... and holding the door for her," before they entered the lobby and headed to the elevator together.

While Tristan has yet to respond to the numerous cheating allegations, he reportedly planned to start his own athletic apparel brand. In some documents obtained by E! News, the 27-year-old athlete filed request to trademark for "Athletic apparel, namely, shirts, pants, jackets, footwear, hats and caps being hardware, athlete uniforms."
