As if things couldn't get worse...

Tristan Thompson's estranged father Trevor is threatening to write a tell-all book about his NBA star son's relationship with Khloe Kardashian, and he's ready to expose all the lies and cheating in the process!

"I have a big, big story about what happened. I can write a book about what happened,” he told Radar, adding that when he does so it’ll be both “really good and sad.”

The athlete's dad thinks that TT's upbringing in a broken home contributed to his bad behavior.

"Tristan needs to communicate with his father so he can be a better person to me and to others. If Tristan was communicating with me, these problems would not happen. Mothers can’t get through to the son the way the father would be able to," he told OK! magazine.

The hits just keep on coming! The baller was benched for his team The Cleveland Cavaliers first-round playoff home game against the Indiana Pacers last night.
