Kellan Lutz and his smokin' hot "
90210" girlfriend
AnnaLynne McCord soaked their smooth, ripped and hairless bodies in the waters of St. Maarten this weekend.

Hopefully they used protection.
Shannen Doherty may have tried two-stepping the California taxman, TMZ has learned.
On March 22 just days before Shannen was booted from "
Dancing with the Stars," the State of California slapped a $44,064.58 tax lien on the "
90210" star.
So far, no comment from her people -- but we're guessing a few more "
DWTS" paychecks would have really helped.
UPDATE: Shannen's peeps tell us this was the first she'd heard about the lien and that it would "be taken care of promptly."

Trevor Donovan showed off his genetically superior talents to some fans in L.A. on Thursday.

Teen boys didn't look like this at our high school ... because Trevor is 31.
Rihanna doesn't completely hate the sound of
Chris Brown's voice -- in fact, she claims she still listens to his music.

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 L.A. home of
Dr. 90210 -- aka
Dr. Rey -- was also pinpointed on the computer seized from suspect
Nick Prugo ... but lucky for the good doc, his place was never pilfered.

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."

Trevor Donovan showed off his perfectly ripped and smooth body at a store in L.A. on Tuesday.

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!

AnnaLynne McCord likes to blow on camera.

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...
Splashing with their girlfriends and sucking on Sugar Factory Lollipops in their bikinis,
AnnaLynne McCord and her equally hot-bodied sis had all the right moves yesterday at
Wet Republic.

Consider this penance for MGM -- who threw
a party for Jon Gosselin the day before.
We'd never heard of
Trevor Donovan before -- but we're paying attention now.

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.
It was another hot one in Malibu this weekend -- and never one to miss a shot at free publicity,
AnnaLynne McCord grabbed her bikini, rounded up a few hot girlfriends and found a spot on the sand to shamelessly writhe on.

...not that anyone's complaining.
We
could tell you all about how
AnnaLynne McCord played paddle ball with her friends this weekend -- but all you really care about is watching her do the
Beyonce booty shake and roll around the sand in her skimpy bikini ... so enjoy!
