90210

In an interview today with The Bert Show on Q100 Atlanta, Rihanna said that despite their battered past, she misses her ex -- and still listens to his songs when they come on the radio.

As for that rumor she's dating "90210"/"The Wire" star Tristan Wilds, she claims they did hang out at a house party she threw, but she didn't even get his digits.

The yellow thumbtack graphic seen piercing the roof of Dr. Rey's L.A. pad was placed there by someone using the computer -- and judging by the thumbtack that marked burglary victim Orlando Bloom's house ... Dr. Rey may have gotten lucky.

Granted, Dr. Rey is a self-proclaimed black belt ... so his mad skills for whoopin' ass could have scared any potential burglars away.

Rey's wife tells us: "My body is shaking all over. It's so scary! Thank goodness they were caught ... I will have to add extra locks to our doors ... It's very scary that it is so easy to find where people live online."

There's a reason why the average teenager doesn't have a physique like his ... because Trevor is 30.

Eat your heart out, Andrea Zuckerman!

Since March, it seems the 22-year-old has been giving photographers the ultimate kiss-off, striking the same exact "spontaneous" pose time after time ... after time.

Stars who don't keep things fresh often lose their appeal...

Consider this penance for MGM -- who threw a party for Jon Gosselin the day before.

Donovan -- and his ridiculous stomach -- will be attending West Beverly High after joining the cast of "90210" for the new season.

Though he'll be playing a high schooler, Trevor's actually 30 -- so drool away.

...not that anyone's complaining.

It all went down outside of MyHouse nightclub, when a group of guys including Brandon Michael Vayda -- who plays Mike on the show -- got into a screaming match with another group of guys over something that was probably stupid and meaningless.

All of a sudden, a couple of guys from each group began throwing punches at each other while Vayda stood and watched. But moments later, after the other group retreated, Vayda stormed into a taxi, and threw several elbows and punches at one of the guys.

Vayda managed to take the guy out of the cab and onto the ground, where he continued to rain down on the guy with a flurry of bombs to the face.

TV show aside, she was actually a pretty cool chick ... but we gotta ask, who spends 12 hours in a spa!?

One of the doctors featured on the reality show "Dr. 90210" is being sued by a former patient who claims some very "personal" body parts were damaged during a procedure at the doc's Laser Vaginal Rejuvenation Institute of Los Angeles.

According to a lawsuit filed today in L.A. County Superior Court, Dr. David Matlock is being accused of causing Patricia D'Edgido to suffer "extreme and severe permanent personal injuries" after a 2007 surgery "on her buttocks and other areas of her body, including her arms and vaginal area."

Among the allegations in the lawsuit, Patricia accuses the doc and the institute he founded of "the use of an improper surgical technique, the artless execution of surgical technique, including the manner in which defendants performed such surgery ... failure to perform the correct surgical technique."

Now Patricia is looking to snatch more than $25k for her troubles.
