Ronda Rousey has signed a contract to fight in the MAIN EVENT at UFC 157 in February ... the first ever female fight in UFC history ... TMZ has learned.

Sources tell us the 25-year-old Olympic medalist will step in the ring with 28-year-old Liz Carmouche ... a highly-ranked MMA badass who served in the U.S. Marine Corps.

The fight is set to go down on Feb. 23 in Anaheim, CA.

FYI -- Carmouche has a 7-2 record and an awesome nickname -- The Girl-rilla.

Ronda Rousey ain't ashamed to say it ... she's all about banging dudes before she steps into the octagon -- thereby cementing her place as the coolest chick in sports.

The MMA champ revealed her pre-fight sex rituals with Jim Rome on Showtime ... saying, "I try to have as much sex as possible before I fight, actually."

Rousey says the old theory about no sex before fights doesn't apply to female fighters because making the beast with two backs increases testosterone levels in women -- clearly a plus before brawling.

TMZ broke the story ... Ronda is jumping to the UFC to become the league's first female fighter.

The punches were real ... the blood was real ... and now former WWE champ Bautista has chalked up his first real win in an actual MMA fight.

Bautista stepped in the ring on Saturday night with Vince Lucero -- a veteran MMA brawler turned bona fide fat person.

Lucero threw a couple of good shots during the fight ... but in the end, Bautista was too strong for the veteran. The ref stopped the fight at 4:05 in the opening round when Bautista mounted his opponent and rained down with a flurry of undefended punches to the head.

With just hours left until his MMA debut, former WWE champ Bautista has been prepping for his big match by hanging with an experienced fighter ... "Real Housewives" star Teresa Giudice.

TMZ obtained a photo of the two kickin' it at a hotel in Rhode Island -- where the 43-year-old will get in the ring for the first time ever on Saturday night to take on Vince Lucero.

Turns out Teresa the table-flipper is in town for a breast cancer awareness event and just happened to be staying at the same hotel as Bautista. We're told the two immediately hit it off ... and even had a convo about MMA.

As for the fight, Dave's rep tells TMZ he plans to watch the Bruce Lee classic "Enter the Dragon” in his hotel room tonight because "it's the greatest martial arts movie ever made."

Bautista's very first professional MMA fight was nearly scrapped this week when his opponent was arrested for a probation violation ... but TMZ has learned organizers have dug up a replacement fighter just in the nick of time.

The fight has been in the works for months ... the ex-WWE champ was slated to get in the ring with Rashid Evans (not the one from the UFC) at a CES MMA event in Providence, Rhode Island.

But a rep for the event tells us ... Evans was scratched from the fight card when he was arrested for violating his probation some time last week ... and once again, it seemed like fate was going to prevent Bautista's MMA career from ever getting started.

Event organizers scrambled to find a replacement fighter -- a guy named Vince Lucero stepped up ... which could be a HUUUUGE problem for Bautista because Lucero has been in more than 40 pro fights.

In fact, Lucero has gone toe-to-toe with a bunch of legitimate MMA studs ... including former UFC Heavyweight champ Tim Sylvia (Sylvia won that fight).

The fight is still scheduled to go down Saturday at 8pm ET.

MMA fighter Muhammed Lawal -- known as King Mo -- wants to kick some serious ass this summer when he joins TNA wrestling ... so much so he's reaching out to some MAJOR ring legends for advice.

The former Strikeforce champion tells TMZ ... as a lifelong wrestling supporter, he doesn't want to disappoint any fans when he steps into the ring. So in order to prepare ... he called wrestling stars Hulk Hogan and Sting for some pointers.

We're told Hulk and Sting imparted their wisdom by telling Mo "just to learn and have fun" with it.

For those unfamiliar with the world of wrestling ... Mo is breaking barriers by fighting with two different companies -- Bellator (which is MMA) and TNA Wrestling -- simultaneously in a joint deal.

Icing on the cake ... Mo tells us several other MMA fighters have reached out to him with interest in crossing over as well.

MMA legend Fedor Emelianenko ... SUCKS ... and he SUCKS HARD ... this according to UFC president Dana White.

White and Fedor have been at each other's throats for months ... a feud which reportedly began after the legendary Russian fighter -- who many claim to be the greatest mixed martial artist who ever lived -- refused to sign a deal to fight in the UFC.

Fedor's manager reignited the war just last month ... when he compared White to a greedy "dog" who runs the UFC like a prison.

But White fired back last night on his way out of Mastro's in L.A. -- telling photogs, "Fedor sucks man ... you guys need to get with the facts, deal with it ... he sucks. Get over the Fedor thing."

UFC fighter Jason "Mayhem" Miller was arrested last week for assault ... TMZ has learned -- after the fighter allegedly put his sister into a headlock and refused to let her go.

Law enforcement tells TMZ, Miller and his sis were at some house party in North Carolina -- when his sister decided she wanted to take off.

According to law enforcement, Jason's sister claims he wouldn't let her leave -- and put her into a headlock.

We're told Jason's sister managed to escape and notified the Chatham County Sheriff -- who had Jason arrested later that evening for simple assault and false imprisonment.

Last night, the UFC badass hit the L.A. bar scene -- hard -- and on his way out, dude startin' jokin' around with some cops outside one of the watering holes. Josh thought it would be funny to "borrow" one of their helmets ... but they weren't laughing.
