Tommy Lee and Son Brandon Trade Angry Messages on Fathers Day

On Father's Day, Tommy took to Instagram to post a note criticizing Brandon and his other son, prompting Brandon to respond with an angry message that reportedly included a video he shot of Lee after knocking his father out.

Founding Mötley Crüe drummer Tommy Lee and his son Brandon, whose mother is Lee's ex, Pamela Anderson, have taken their feud to social media, three months after Brandon assaulted his dad at Lee's home.

In Lee's message, he said his own father taught him "to respect everyone…to appreciate my possessions, and to be grateful for the things I was given." He then noted, "Sometimes I feel like I failed as a father, because my kids don't know the value of things."
