Apparently not happy with the way their online altercation on Father's Day (June 17th) ended, Motley Crue drummer Tommy Lee has posted another swipe at his 22-year-old son Brandon on social media. After Brandon shared some of their turbulent recent history -- even revealing that Tommy did not call his son for his birthday on June 5th -- Tommy posted a tweet in which he tallied up the costs of various things in Brandon's life he paid for, including a stint in rehab.

Tommy tweeted, "Rehab for son: $130,000...Party for son’s 21st birthday last year: $40,000...Medical Bills after son knocks his father unconscious and uses 'alcoholism' as scapegoat: $10,000...Son acting like a victim on social media on father’s day: Priceless." He then posted an image signifying a mic drop.

This all began last Sunday when Tommy took to Instagram to honor his dad, while remarking on his own failures as a father. He wrote in part, "Sometimes I feel like I failed as a father, because my kids don't know the value of things . . . I love my boys but they can be a****les too and that's the truth (Cue Honest Guy music)."

Brandon later fired back, "You gotta show up to be a Dad big guy. 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."

A follow-up post, later removed, contained a video of an unconscious Tommy lying on the floor in a T-shirt and underwear -- the footage apparently taken during the alleged March brawl between father and son. Brandon has yet to reply to his dad's latest missive.
