Ben Stiller mugged for the cameras at their "Zoolander 2" premiere -- and by mugged we mean he and his son went full Blue Steel.

Stiller and his wife, Christine Taylor, made it a family affair with their kids Ella and Quinlin at the world premiere of "Zoolander 2" at Alice Tully Hall in New York Tuesday night.

The family stopped to pose on the purple carpet and Stiller's son grabbed the spotlight and flashed a perfect Blue Steel to the crowds.

Stiller's been on a tear promoting "Zoolander 2" in Milan at a department store and breaking a record for exposing his ultra-long stick.

Amber Rose and Blac Chyna are twinning in Trinidad where the Carnival celebrations are looking bigger than ever.

The ladies proudly displayed their assets while hosting one of the many parties going down on the Caribbean island.

We can tell you what the men of Trinidad are NOT giving up for Lent!

Disneyland is the most hungover place on Earth ... if Peyton Manning slammed as many Budweisers as he threatened to after Super Bowl 50.

Peyton and his 4-year-old twins Mosley and Marshall are in Anaheim right now, and hitched a ride with Mickey, Minnie and co. for a victory parade -- his last one at Disney if he decides to retire.

Manning's kids are loving this, but the Broncos QB clearly has only one thing on his mind: Where's the beer??

Hair o' the dog! (No offense, Pluto)

Hilary Duff and Mike Comrie are now officially divorced, but before the ink dried on the docs they hit the beach together in Hawaii with their kid.

As we reported, the divorce became final last week. They have joint custody of their 3-year-old son, Luca, and despite some hard feelings between Hilary and Mike when the divorce papers were filed, they are clearly working the whole co-parenting thing out.

Justin Bieber may have started a new holiday by pulling a late night recording session with his grandfather!

Biebs hit up a studio in Santa Monica on Wednesday with grandpa in tow. Justin's done stuff with gramps on social media, but this is the first time we've seen them hang together at work.

Here's a couple of the dynamic duo's greatest hits ... so far.

Even when Serena Williams loses on the court, her body still dominates off it -- exhibit A was spilling out of her shirt Wednesday night in L.A.

Serena hit up celeb hotspot The Nice Guy in a severely buttoned-down shirt ... showing off most of her black bra and a ton of cleavage.

While she might still be stinging from that Australian Open loss last weekend, this should help Serena's fans recover.

Zach Galifianakis' dramatic weight loss has gone next level ... even the guy's beard is thinning down!

The funnyman looked like a fraction of his Carlos-toting 'Hangover' character on his way into lunch Wednesday in Venice.

Zach's said he dropped the lbs through healthy eating and less boozing. Whatever he's doing looks wayyy better than any of the 'Hangover' sequels.

Especially #3.

O.J. Simpson's daughter, Sydney Simpson, has resurfaced in St. Petersburg, Florida. She was quietly living there, until the swell of interest over the FX crime drama about her father.

Sydney, now 30, blended in with the rest of her neighbors doing the usual errands ... taking out the trash and walking her dog.

You can't help but feel bad ... Sydney was 8 and her brother, Justin, only 5 when their mother, Nicole Brown Simpson, was nearly decapitated at her Brentwood condo while they both slept upstairs. It's almost unthinkable ... but O.J. left Nicole's body for her kids to find. Luckily, cops intervened.

Florida ... a long way from Las Vegas, where O.J.'s currently in prison for a different crime.

Gigi Hadid and boyfriend Zayn Malik left The Nice Guy Tuesday night looking like they wished they'd opted for Netflix and chill, instead of hitting the L.A. hot spot.

The couple looked pretty sleepy on their way out, and Gigi dropped her head on Zayn's shoulder as soon as they got in their ride.

Even former 1D-ers have dud nights sometimes.

David Bowie's wife Iman put on a brave face walking the family pooch Tuesday in NYC.

It's the first time Iman's been seen in public since Bowie passed away last month from cancer. She tooled around her Soho neighborhood and, gotta say ... she looks amazing.

Hard to believe she's 60 ... dog's cute too.

Guy Ritchie was tooling around London Wednesday -- the same day the NYC courtroom showdown with Madonna was scheduled -- but he didn't miss a thing, because the hearing's been put off a month.

Rocco's been living with his dad since the beginning of December, insisting he didn't want to go back and live with his mom. Rocco's position hasn't softened. It appears he hasn't returned to NYC to even visit.

Kourtney Kardashian and Scott Disick packed on a little PDA Tuesday ... which makes you wonder.

They were shopping at Williams-Sonoma in Calabasas when they got all handsy with each other.

CAUTION ... "Keeping Up with the Kardashians" cameras were rolling, so things may not appear as they seem.

Fact is ... Scott just bought a new home near Kourt so we're guessing she was just helping him pick out a Dutch oven.

Jaden Smith really does have a direct line to God -- or at least Elon Musk -- since he managed to score one of the first new Tesla SUVs.

Jaden was stuntin' in his Tesla X Monday evening in L.A. ... as well he should -- the brand new vehicle's release has been delayed more than a year. Even people who put in early deposits have had to wait and wait and wait.

The fully electric whip, with those awesome falcon-wing doors, does 0 to 60 mph in 3.2 seconds.

Jaden's called himself a prophet. At this point, who the hell are we to argue?

Rob Kardashian and Blac Chyna are back in L.A. County ... 2,800 mile road trip in just 3 days.

Rob and Chyna were spotted in Beverly Hills Monday morning, which means Rob has driven virtually nonstop the entire weekend.

TMZ broke the story, Chyna was arrested Friday at Austin International Airport for being drunk and disorderly. She was also busted for possession of ecstasy.

Rob literally jumped in his Bentley minutes after Chyna's arrest, drove for more than 20 hours to Austin, and then turned around with his prize and returned to L.A.

12:00 PM PST -- Looks like Rob dropped Chyna off at a laser specialist to get her "Future" tattoo removed.

Ariel Winter enjoyed the spoils of turning 18 ... partying at an L.A. hot spot and showing off her body -- so we're guessing her BF had a good time too.

The "Modern Family" star and Laurent Gaudette hit up The Nice Guy Sunday night where she celebrated her recent 18th birthday in an outfit that was long on legs, and heavy on cleavage.

'Vampire Diaries' star Nina Dobrev does not fear the sun.

Dobrev, who left CW's hit show last year after six seasons ... soaked up the surf and sand over the weekend with her pals in Maui.

Nina's found new and exciting ways to entertain us.
