Matthew Fox is in trouble this morning after it’s been reported that he punched a female bus driver in the face! And that’s not all – according to witnesses, Matthew also punched her in the boob – and crotch (see below)!!

Matthew Fox was detained by cops in Cleveland, Ohio Saturday night after allegedly assaulting a woman outside of a bar … TMZ has learned. Law enforcement sources at the scene tell us … the “Lost” star allegedly tried to enter a party bus — even though he wasn’t a guest on the vehicle.

We’re told the woman who was driving the bus tried to block Fox from getting on board — at which point, he allegedly punched her in the breast and the “stomach area.”

Fox was handcuffed by an off-duty officer — and was later detained by police. Fox was released without being formally arrested. An assault report was taken and the matter remains under investigation.

We have not been able to reach Fox for comment.

UPDATE: According to the police report, obtained by TMZ, the woman PUNCHED BACK — and struck Fox “in the mouth … causing a cut on his lip.” The woman told police she may have broken her hand during the altercation. Fox was later released to a friend … who put the actor into a taxi and accompanied him back to his hotel.

Can you believe that crap! What an egotistical pig! Just because he’s a celebrity doesn’t mean he gets whatever he wants! What I love about this story – is the bus driver fought back!

It’s long been reported that Matthew is a cheater, maybe he just dislikes women.

The woman who punched Matthew Fox in the face this weekend tells TMZ … she HAD to let her fists fly because the actor struck first and she needed to defend herself. TMZ spoke with Heather Bormann … who tells us she was driving a party bus for a private party Saturday night in Cleveland — when Fox boarded the vehicle.

Bormann claims she told Fox he wasn’t welcome on the bus — but he was too drunk to understand. Bormann says, “He just kept staring at me with his mouth wide open and not saying anything. I told him, ‘You have to leave buddy. You are trespassing on my bus.’”

That’s when Fox “leaned in and started punching my crotch and breast.”

Bormann says, “I took one hand to his jaw and he was spitting blood. He stumbled backwards.”

“This was my self-defense,” Bormann says … adding, “This was the only way I could protect myself…..from a man beating up on a woman.”

Bormann says she’s meeting with prosecutors today — and may press charges.

I really want to love my fellow Oregonian Matthew Fox, but this story is just plain disgusting. Who hits a girl in the boob and crotch!? Seriously!

Lost actor Matthew Fox has wrecked his clean-cut image by confessing his drug-taking past. Speaking to British movie magazine Empire, Fox admits he has taken “plenty of illegal narcotics,” regularly breaks the law, and is a secret naturist.

He says, “I break the law all the time! I’ve done plenty of illegal narcotics, but I think everyone knowingly breaks the law pretty often, don’t they? I can’t imagine living my life abiding by the law completely. That’d be tough to do.

“My wife and I traveled to Jamaica 15 years ago. Oh God, it was a crazy trip! We stayed in this little bungalow out on the water, baked out of our minds for the first three days. We were just so stoned! And then we got sick and proceeded to continue to get stoned because that makes you feel better.”

Fox adds of his love of being naked: “I’m naked outdoors a lot – I live in Hawaii – if naked outdoors means walking out to the pool naked and jumping in and walking back inside.”
