Check out the details behind Ronda Rousey’s defeat on the next page…

Rousey fell from grace after a second round knockout from fighter Holly Holm last night (November 14).

The 28-year-old MMA fighter was defeated barely under one minute into the second round during her UFC 193 fight with her opponent on Saturday. Holm, 34, delivered a swift kick to Rousey’s head and down she went. Her loss is being touted the biggest UFC upset in history. (E! Online)

Last year, Rousey responded to a diss lyric rapper Eminem shot at her on his “Shady XV” song.

“Yes, yes, I’m very aware,” Ronda responded when asked if she knew about Em’s diss. “He’s a great artist and art isn’t meant to be nice. It’s meant to make you feel something. I don’t know and I don’t really care. [Is is insulting?] I don’t know. I like being called a slaughterhouse in a blouse. I think it’s cool and I might not be perfect but parts of me are pretty awesome and I think if Eminem took the a** Pepsi challenge, he would totally pick me as his favorite.” (“Jimmy Kimmel Live!”)

On the track, Slim Shady takes direct aim at the mixed martial arts fighter.

“I got a Magic Johnson
/It’s like a Magic Wand allows me to not let a blonde arouse me
/If Ronda Rousey was on the couch with the condoms out
/Holding a thousand Magnums at once to pounce me
/I’ll laugh in response to how she dances and flaunts it around me
/Her flat little badonkadonk is bouncing around
/And all I see is Paulie Malignaggi, she’s slaughterhouse in a blouse” (“Shady XV”)
