Mötley Crüe drummer Tommy Lee reportedly called the police on his son Tuesday evening after an altercation between the two.
In an Instagram post that he later deleted, Lee posted a photo of his swollen mouth, saying it was the work of his 21-year-old son Brandon Lee.
Lee's photo was accompanied by the caption, "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."
Police responded to Lee's home, according to People, and Lee later visited the hospital. Brandon Lee, one of Tommy's two sons with Pamela Anderson, was not arrested and told TMZ that it was his father who attacked him.
The drummer later Tweeted that he and his fiancé Brittany Furlan were in bed when Brandon "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."
On Monday, Tommy Tweeted in response to his ex-wife Anderson's recent interview with Piers Morgan in which she recalled Tommy's 1998 arrest for spousal battery. Tommy pleaded no contest to the charges and spent six months in prison for the offense.
In the Tweets, Tommy called out Morgan for rehashing the painful incident and called out Anderson having "nothing else going on" and needing attention.
He then added that Anderson texts him everyday and "asks for me back."
Also on Tuesday, Lee shared a video via Instagram story of a dirty bedroom which he claimed belongs to Brandon.
TMZ reports that Brandon was confronting his father regarding the Tweets about Anderson and about Tommy's alcohol use.
Brandon says his father was drunk when he lunged and him. Brandon says he punched Tommy in self-defense. The 21-year-old says he wants his dad to get sober.
As of this morning, Lee said he planned to press charges against Brandon, who is being investigated for criminal battery.
Lee's fiancé Furlan later Tweeted, "Violence is NEVER the answer. No matter the situation. People need to learn to talk things out, not throw punches. It’s not necessary and doesn’t solve anything."
