Oh no he didn't! Just when you thought Tristan Thompson couldn't get any worse, it is being reported that the NBA star also cheated on Khloé Kardashian the night before her baby shower. Since his cheating scandal exploded earlier this month, several women have come forward claiming to have slept with the basketball player during Khloé's pregnancy.

With five alleged side pieces, it's hard to believe each story — including the rumor that he was unfaithful before True Thompson's baby shower. It also doesn't help that Tristan was spotted at LA hot spot Delilah on March 9, without the KUWTK star. Coincidence? We think not. Watch the video for what a source revealed about the alleged infidelity.

Just days before the arrival of their baby girl, Tristan was caught cheating on Khloé with Instagram model Lani Blair in NYC. Since then, more women have come forward with cheating allegations of their own. Back in February, In Touch revealed that Tristan was spotted flirting with a mystery woman — and it was worse than Khloé can imagine. “She slept with him because he's an NBA star, but she thinks he’s hot, too. She said that the sex was good too," an insider explained. "He was definitely not careful at all about making sure that nobody knew who she was or that she didn’t have her phone."

The source also confirmed that Tristan did not use protection, adding, "He texted her, ‘Do you have Plan B?’" This must explain why Tristan is begging for Khloé's forgiveness in Cleveland. "[Tristan]'s been in Khloé's ears apologizing, telling her that these videos aren't what they look like," another source told In Touch. "He's telling her that the girl he was with at the hotel is [a friend of a friend] and that the video of him kissing that chick last year was a stupid bet he made with one of his teammates."

You know what they say — Once a cheater, always a cheater.
