Their feud started back in March when it was reported that police responded to a call to Tommy's house in Calabasas because the rocker was allegedly punched by his 21-year-old kid.
"My fiancé and I were in bed when my son busted into the room and assaulted me. I asked him to leave the house and he knocked me unconscious. He ran away from the police. THAT’S the truth,” Tommy tweeted.
The musician later shared a post on Instagram and captioned it with, "My heart is broken. You can give your kids everything they could ever want in their entire lives and they can still turn against you."
While Tommy portrayed himself as the victim in the scenario, Brandon, whose mother is model and actress Pamela Anderson, had a different side of the story to tell.
He said Tommy's allegations weren't entirely true and that the altercation happened after he tried to stage "an intervention" for his father's addiction.
"I'm devastated at the events of the last several days that have been a result of my father's alcoholism," the model wrote in a statement. "I've worked tirelessly organizing an intervention and it's incredibly upsetting that it never came to fruition. I wanted my dad's hopeful sobriety and recovery to be a private family matter but, as a result of his accusations on social media, I feel forced to speak out."
He said that he would "continue to cooperate with law enforcement," and that he loves his dad and "just want to see him sober, happy, and healthy."
Tommy responded to Brandon's statement on Twitter, calling it a lie and announced that he was
leaving social media because he "can't read anymore liesss."
"LMAAAO!!!! I'm happier than I've been in my entire life," wrote Tommy. "I have a few drinks here & there because I'm f***in' retired and enjoying my life. I worked 30+ f***kin' years I deserve it. You didn't arrange any intervention, you barely spoke to me while u were here. Just coverin ur a**!! See ya later social media!"
According to celebrity news website TMZ, Pamela later came to her son's defense backing up his claim that he wanted to help his father. She confirmed that Brandon was planning an intervention with "friends and people Tommy works with and admired."
After a brief investigation, the District Attorney's office refused to file charges against Brandon, and the family appeared to have gone back to normal.
However, a few months later, the feud seemed to have escalated after Brandon posted a video of
his father unconscious on the floor.
“Look a little sleepy there Tommy," Brandon captioned the clip, which was shared on Instagram on Father's Day.
Brandon then responded to his dad's Father's Day message with another post on his Instagram page.
"Remember what happened last time you said this s**t? 🤔 night night 😴 You gotta show up to be a Dad big guy," Brandon wrote in the caption. "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 f**k are you? Just move on dude... WE ALL HAVE. ✌🏼or I’ll put you right back to f***in' sleep 😴"
Tommy has not reacted to any of Brandon's comments, but in his Father's Day message, he admitted that fatherhood is a "rollercoaster," before blaming Pamela for the way Brandon and his younger brother Dylan, 20, are acting now.
"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."
He concluded, "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 (expletives) too ... and that’s the truth (Cue Honest Guy music)."
While Pamela has not addressed this controversy yet, she has previously sided with her son.
After the last incident, she told TMZ that her ex-husband is "consistently the center of sadness, drama and confusion, jealous of his sons' talent and beauty from the day they were born. He is sick. The definition of narcissist/sociopath."
"He still cannot handle the guilt about his abusive behavior and has never taken responsibility for what he has done. He [Brandon] punched him in the nose for all of us who he has hurt. Now Tommy feels humiliated - and is attempting to destroy his own son. This is the Devil - This is the disease of alcoholism."
Past reports revealed that Tommy was considering a restraining order against Brandon, but it's unclear if he is still planning to go through with filing for it.
