Mötley Crüe drummer Tommy Lee is no stranger to being in the headlines, but it's not always about his music.
A controversial figure, to say the least, Tommy has bee involved in a number of legal troubles, including serving a six-month prison sentence in 1998 after pleading no contest to abusing his then-wife, actress and model Pamela Anderson, whom he married in 1995, four days after they met.
According to reports, Lee assaulted Pamela and left her with "bruises, a torn fingernail, and fear for the safety of her two sons, Dylan and Brandon."
The dysfunctional couple got divorced in 1998, but briefly got back together after Tommy was released from jail, before parting ways once again in 2001.
While Pamela moved on to better things, Tommy's violent streak continued to get in his way. They made up again in 2008 for the sake of their children, but that did not last long either.
He was arrested for assault on multiple occasions, including at the 2007 MTV Video Music Awards when he got into a fight with singer Kid Rock.
It's been over a decade since that incident took place, and Tommy seemed to have been staying out of trouble, until now.
It seems like the rocker isn't the only Lee with a violent side. According to People, police was called to Tommy's house in Calabasas after he was knocked unconscious by his oldest son, Brandon.
"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.
He later took to Instagram to share a photo of his busted lip. He 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."
However, 21-year-old Brandon's side of the story is very different from his father's.
