Ronda Rousey and Holly Holm nearly came to blows, and the champ is furious

The champ is pissed, and that can't be good news for Holly Holm.

Ronda Rousey will face arguably her toughest competition to date Saturday night in Australia, when the Bantamweight champ does battle with Holly Holm.

During the weigh-in, things got a bit testy and a matchup with no real drama now has plenty of it.

Rousey got in Holm's head, placed her fist where the challenger usually does and things only got more heated from there.

And here's the scathing caption from the champ's Instagram post:

"Fake ass cheap shotting fake respect fake humility bitch - "preacher's daughter" my ass - I see through your fake sweet act now - you're getting your ass kicked tomorrow, and I'm really going to enjoy the beating I give you #andSTILL"

UFC 193 kicks off at 10 p.m. ET, and the Rousey-Holm bout likely won't go on until midnight ET.
