Miesha Tate -- Ronda's Emotionally Unstable

Miesha Tate says Ronda Rousey is "somewhat emotionally unstable" -- and says it explains why the UFC legend went off on Paige VanZant at a party last month.

Tate appeared on Rush Fight Club on SiriusXM -- and went off about the issue when asked about the April encounter, when Rousey cussed out PVZ for congratulating Holly Holm after UFC 193.

"I think Ronda is somewhat emotionally unstable and I think that's been characteristic for a long time," Tate said.

"Doesn't mean she fights any worse for it. I'm not knocking her as an athlete but emotionally she's just got some things that are a little bit strange and I think that that was one of them."

Tate says the incident brought her even closer with VanZant -- despite the fact Tate says she would've handled the encounter in a much different way.

"This is why I feel like I identify with Paige more. She's so kind and when this whole thing happened she was like, 'We're emotional beings and hopefully I can make it right with Ronda,' and she's still such a sweetheart but I'm not that way."

"When Ronda does things like that to me I'm just like, 'No, eff you.' I'm not gonna bow down and not say how I feel."
