This feud can't get much worse!

Tommy Lee marked Father's Day by slamming his sons and their mother Pamela Anderson on social media, so his eldest Brandon fired back by posting a pic of the rocker unconscious in his underwear after being knocked out following their fist fight a couple months ago.

"Happy Father’s Day fellas! I’m not gonna sit here and post some fluffed up bullshit for the public to read.... I’m gonna be honest- Being a father ain’t easy! I’m so tired of the fake shit I keep seeing all over IG... let’s get real: It’s a rollercoaster ok? My father taught me to respect everyone and everything and to take care of those that I loved. He taught me to appreciate my possessions, and to be grateful for the things I was given. I’ve fucked up at times but I’ve always bounced back," Lee wrote on Instagram.

"When I had a child, my first child, I wanted to instill those same virtues into him. Sometimes I feel like I failed as a father, because my kids don’t know the value of things. If they break something, they don’t care because they know they’ll just get a new one, if they hurt someone, they don’t care because so many people tell them it’s OK. I never wanted this for my kids," he continued.

"I know I’m not fully to blame, because their mom has a lot to do with it, enabling bad behavior and buying them things when they weren’t good, but I guess I hoped at the end of the day they would end up kind. I love them dearly, don’t get me wrong, but man, sometimes it’s really tough to watch your kids grow up without those morals. Nothing can really prepare you for fatherhood .... I love my boys but they can be assholes too...and that’s the truth (Cue Honest Guy music)," he concluded.

That's when Brandon went OFF!

"Remember what happened last time you said this shit? 🤔 night night 😴 You gotta show up to be a Dad big guy. If you think we’re so bad (which I can assure you we are not) then you should have showed up to a few more BDays and baseball games. Someone like you couldn’t raise a man like me. Once again painting our family in a negative light. Who the fuck are you? Just move on dude... WE ALL HAVE. ✌🏼or I’ll put you right back to fuckin sleep 😴," the 22-year-old wrote along with the embarrassing clip.

He might want to be careful about biting the hand that feeds gives him money!
