Rihanna Hawaiian Ass Pic ... Dem Buns Are Da One

It's funny that Rihanna is the one in Hawaii ... because we're the ones enjoying the view.

RiRi is island side for the marriage of long time assistant Jennifer Rosales -- going down Monday -- but instead of taking in epic shots of perfect sunsets, she spent a lot of time this weekend snapping selfies of her perfect parts ... and we ain't complaining.

Front, back, side to side ... she definitely got all the angles ... but the trip isn't about her, right? It's about love and marriage and ... blah, blah, blah.

That pizza slice bathing suit is on point ... and if she's offering, we'll take a piece.

Kylie Jenner Girls Want Her Fat Lips!!!

0-kquht9hm
LIP SERVICE

Kylie Jenner pretty clearly has a fan base that wants her lips, whether they're real or not.

Truth be told, our office is divided. The guys think these girls in the video are mocking Kylie by putting their lips inside a bottle to swell them up, but the women in the office say the girls are trying to be just like the youngest Jenner. Since the men here have never been teenage girls, the women win.

The hashtag, #kyliejennerchallenge, is blowing up.

Kylie's lips ...

BTW Kylie has insisted in the past, "These plastic surgery rumors hurt my feelings to be honest and are kinda insulting ... Just in case anyone forgot... I'm 16."

Selena Gomez Swimsuit Upgrade It's All About the Fit!

Selena Gomez ditched her ill-fitting pink bikini for a smoking hot black number as she partied again Thursday in the water while on vacation in Mexico.

Gomez took some flak for the previous day's photos -- haters said she looked like she put on a few pounds -- but swimsuit experts (in our newsroom) say this black one just fits her new body type WAY better than the pink one.

Selena responded to the criticism on Instagram -- borrowing a page from the Cindy Crawford "post a hot pic after a bad one comes out" playbook -- saying she's happy with her body.

Based on the pics she's posting ... she's also very happy chillin' at Casa Aramara -- Joe Francis' estate outside Puerto Vallarta.

Selena Gomez Body Banging, Bikini Clinging ... Pinky Swear

Selena Gomez didn't pull any strings in Puerto Vallarta ... dammit.

Biebs' former squeeze was showing off the goods during her Mexican vacay ... sporting a double-stringed bikini bottom thingy (we know fashion).

There's not a ton of material to her ensemble, but what there is -- is definitely working overtime to cover the 22-year-old's assets. Things are getting thick down in Mexico.

It's high-season for tourism.

Gisele Hottest Retirement Party ... Ever!

Sad day for the fashion world, and an even sadder one for the guys-ogling-hot-chicks world -- Gisele Bundchen has walked her final runway ... at 34.

The modeling legend -- whose career earnings are reportedly near $400 million -- hit the catwalk for Colcci during São Paulo Fashion Week in her native Brazil. She's gonna keep working in the modeling biz, but says she's done strutting for pay.

Hubby Tom Brady, her parents and sister all sat front row for the show. Tom posted a disgustingly drippy love letter to his missus about her accomplishments and inspiration, and blah blah ... but best of all he ends it with, "I can't wait to see what's next. I love you. ?#‎GOAT?"

As long as we remember her in our hearts, she'll never really be gone. Plus, there's still old Victoria's Secret catalogs.

'DWTS' Star Chris Soules Dance-scaping

0-87w4kfj2
OHHH KELLY CLARKSON!

"The Bachelor" star Chris Soules is definitely no 40-year-old virgin ... but he did a damn good impression by getting his chest hair torn out for his next performance on "Dancing With the Stars."

We're told Chris will be channeling Hercules in the dance number, and his partner Witney Carson suggested he clean up that Soules Patch ... of course, she volunteered to wax on, wax off.

We're told he'll wear a skirt to show off his man-gams, and nothing above to showcase his new, smooth chest. We doubt fiancee Whitney Bischoff will complain.

It's painful to watch but it's funny.

Jackie Chan GOOD GENES OR GOOD DOCS?

Jackie Chan's good looks are still kicking ass!

Here's a 27-year-old version of the martial arts expert and "Dragon Strike" actor hanging out in Paris back in 1981 (left) and 34 years later ... the "Rush Hour" vet -- who turned 61-years-old earlier this week -- at a speaking event in Beijing, China (right).

Jackie Chan...

The question is ...

Rumer Willis Asses With Stars ... Just Give Her the Damn Trophy Already

This is Rumer Willis leaving a "Dancing With the Stars" rehearsal -- or more accurately ... it's Rumer's perfect ass leaving rehearsal.

On fleek ... comes to mind.

Rumer's already taken the MVA (most valuable asset) on this season of 'DWTS' -- and a lot of people who give a crap about that show ... think she's a lock to win the mirror ball thingy in the finale.

If she doesn't win ... we'd hate to see her go, but we damn sure ain't gonna be mad watching her leave.

Irina Shayk My Cups Runneth Over ... In Cancun

Here's international supermodel Irina Shayk ... showing off her INSANE physique during a beach trip in Cancun, Mexico.

The 29-year-old's bikini top battled heroically to stay in position as Irina splashed around in the surf ... and while there were several close calls ... it ultimately emerged victorious.

Of course, Shayk recently broke things off with her longtime soccer superstar boyfriend Cristiano Ronaldo -- who's gotta be kicking himself right now ... or banging someone else.

Anyway, check out the pics. Good times.

Kylie Jenner 30 Going On 17

Kylie Jenner hopped in a time machine, and POOF -- just like that she looked like a real life regular 17-year-old again ... a much different look than she's been flaunting lately.

Kylie was refreshingly makeup-free while hanging out with her sister Kendall ... who was doing a
photo shoot Tuesday in Malibu.

Better look for Kylie ...

In recent weeks she's tried out a lot of different looks -- some with less success than others -- but this one might be most revealing of all. Imagine that ... a 17-year-old who actually looks 17.

Kendall Jenner Getting a Rise Out of Easter

The Kardashian klan celebrated Easter Sunday wearing all white ... some less than others.

Kris, Khloe and Kendall all went to West Hills Church in the San Fernando Valley, along with Kris' BF Corey Gamble. A tattered Kanye, Kim and North West also showed. And the non-dating Kylie was front and center with her non-boyfriend Tyga and his son King.

Kendall didn't wear a full outfit to church, and she wore even less for her Instagram photo wishing people a happy Easter.

Praise the lord.

Jessica Alba Bikini Pics Make For a Good Friday

Jessica Alba continued to do what she does best Thursday in St. Barts ... rock a bikini better than pretty much anyone.

We are risen.

I'm Rob Lowe And I'm ... On Vacay Rob Lowe

Here's a version of Rob Lowe we can all get behind ... the selfie-taking one who hangs on the beach in Maui with his wife, Sheryl.

Let's face it, being like any version of Rob Lowe would be a good thing for the rest of us.

Well, except for "Dr. Vegas star Rob Lowe" ... we can all agree that model sucks.

Eddie Murphy's GF Hottest Babysitter Ever

A Maui beach was blanketed by Eddie Murphy's smoking hot chicks this week -- one of them was his girlfriend, but the others were his daughter and the daughter's friend.

Eddie's gorgeous 35-year-old Australian girlfriend Paige Butcher was there with his 25-year-old daughter Bria and one of Bria's friends. Murphy apparently missed out on the fun.

Hands down ... this vacay looks better than almost all of Eddie's movies in the last 10 years.

Jessica Alba Cakes Up for Spring Break With Chrissy Teigen

Jessica Alba still does spring break like she's 23, and she's got the booty to back it up -- as she proved on a Caribbean beach with Chrissy Teigen.

Jessica, Chrissy and John Legend were frolicking in the water Thursday -- and it's almost like Alba's ass knew it had to do something to stand out with so many celebs in one spot.

Mission accomplished.

Not to be a buzz kill, but Jessica's 3-year-old daughter Haven is in the photo too (pink hat).

Sorry. You may now resume objectifying her mom -- and because we have a deep respect for history ... here's a classic.

Amber Rose You Can Touch My Ass ... With An Airbrush

Amber Rose has an ass that just won't quit ... getting Photoshopped -- and here's a little before and ass-ter to prove it.

Amber posted a bunch of Instagram shots from her day at the beach in Hawaii -- and everything was so smooth. But then we got some paparazzi shots of her ass -- it's hard to miss -- and these pics are straight outta dimpleville.

Truth is Amber's in good company -- even Beyonce's been busted multiple times altering pics.

And say what you want about it, but that booty trapped Kanye West AND Wiz Khalifa.

Respect.

And from the no-filters-required department ... we offer these. On fleek.
