Oh, and if you're struggling to wrap your head around why Martha attended a roast for Biebaroni, know that she was arguably the most blunt of the group!
"Justin, before I go, here is my final piece of advice. You need to settle down, bring some balance into your life, find yourself the right gal but she'll have to be someone on your level, someone powerful and famous and rich, someone you can smoke a joint with or indulge in the occasional three-way. I'm talking about a playa in the board room and a freak in the bedroom. So Justin, my final piece of advice is, call me."
Wow! The 73-year-old is NOT messing around! Ha!
But wait, Martha wasn't the only one who got Biebs good -- check out the singer's longtime pal, Ludacris, throwing him some shade (below)!
