Woah Vicky is so serious about taking a real boxing match with arch-nemesis Danielle Bregoli -- she's already started training with a legit boxing superstar, Jermell Charlo.
19-year-old Vicky and 16-year-old Bregoli -- two social media superstars -- already scrapped at a recording studio back in October (the video was crazy BTW) but Bhad Bhabie has been calling for a rematch ... in a boxing ring.
"1 million and I'll fight that horse toothed hoe in the ring," Bregoli tweeted.
Vicky got the message -- and SHE'S DOWN!
