Rocker Tommy Lee gets knocked out cold by his son after posting rude comment about Pamela Anderson online: Report

Tommy Lee got into a physical altercation with his son, Brandon, on Monday night, which allegedly led to the rocker being knocked out so fiercely that his fiancé reportedly thought he was dead.

People reports that deputies with the Los Angeles County Sheriff Department responded to Lee’s home in Calabasas, where they found the 55-year-old drummer with a swollen, bloody lip. His son, Brandon, also the son of Lee’s ex-wife, Pamela Anderson, had already left the home by the time police arrived. Lee was taken to a local hospital for treatment.

According to TMZ, the altercation occurred after Lee posted posted a comment about Anderson on Twitter, after the former “Baywatch” actress opened up about physical abuse earlier this week while taking to Piers Morgan. Sources told the outlet that Brandon charged into father’s bedroom door and challenged him to a fight after demanding he take the tweet down, which Brandon reportedly thought was in bad taste and disrespectful to his mother.

“Think she’d find something new to discuss instead of rehashing old s— but I guess she has nothing else going on & needs attention Signed, ‘The abuser’ (who she texts every day & asks for me back),” Lee tweeted.

Lee allegedly walked up to his son and told him to leave his room, which resulted in Brandon reportedly knocking his father out cold. Lee’s fiancé, Brittany Furlan, called 911 shortly after. Brandon later said that his father aggressively approached him and he had no choice but to punch him in self-defense.
