Charlie Sheen ... GOES TO COLLEGE??

Now, that the Warlock has finally obtained his diploma from Santa Monica High School (30 years behind schedule) ... Charlie tells TMZ college would be "HELLA FUN."

The 48-year-old graduate just called "TMZ Live" to talk about his accomplishment -- and explained how he managed to finally complete HS, even though he only showed up for class 33% of the time.

Charlie also explains why he was so passionate about getting his diploma -- and what he plans to do next.

Check out the clip.

Simon Cowell might be over the shock of becoming a father, at 53, but his reaction to possibly getting married on top of that is down right hysterical -- as in ... "HAHAHAHAHAHAHA!!!"

Simon called in to "TMZ Live" to discuss a possible marriage to baby mama Lauren Silverman -- and his feelings about creating his own little Mini-Me.

Simon boasted ... "If it's a boy, then there will be another me on this earth for many, many more years to come."

As for his reaction to the news he'd knocked up Lauren ... "Gulp!"

But you gotta see Simon's response to the marriage question. Classic ... bachelor.

Lamar Odom's drug-induced paranoia, crack binging, and Khloe Kardashian's jealous rage -- the NBA star's ex "roommate" told the FULL STORY about her summer with Lamar ... and it's wild.

Polina Polonsky was on TMZ Live -- we posted an excerpt where she described Lamar completely unraveling in her L.A. apartment this summer ... smoking crack and becoming paranoid.

Now here's the full monty ... Polina talks about how Lamar practically began behaving like a toddler while living with her -- and how Khloe eventually barged in to her apartment in the middle of the night like an "uncaged animal."

The lawyer who lived with Lamar Odom for 6 weeks in June and July tells TMZ ... Lamar was doing crack in her apartment.

Polina Polonsky is a criminal defense lawyer who met Lamar in the Spring at the Roosevelt Hotel in Hollywood. She told us on TMZ Live ... he was smoking crack and doing other drugs while he stayed with her ... but she says things really spun out-of-control when he moved out.

Polina tells us Lamar became paranoid while he lived with her ... taking the battery out of his phone because he felt he was being followed with the aid of a GPS device. He also covered the smoke detectors with paper towels.

Polina says Khloe Kardashian came banging on the door in July, barged in, took charge and took Lamar out. She received a text from Lamar shortly after he left, calling her a "groupie, junkie ... crack head." She says she knows it wasn't Lamar who sent the text ... it was Khloe.

A$AP Rocky hasn't had the decency to call the woman he allegedly slapped during a concert ... and she tells TMZ she wants to nail him in criminal court.

Lisa Wade --a self-described fan of A$AP -- called in to "TMZ Live" and gave the blow-by-blow ... which she says was a brutal, unprovoked attack.

Wade says A$AP was walking through a surging crowd of people when he hauled off and smacked her ... HARD.

A$AP's been charged with criminal battery.
