Scarlett Johansson and Colin Jost have a hell of a weekend update ... PDAing in Argentina's capital city the day after Christmas.

The 'Avengers' and 'SNL' stars are in the touristy town of Palermo in Buenos Aires. They were total normies ... sightseeing, holding hands and walking arm in arm. It seemed pretty intimate ... nevermind their bodyguard.

The couple spent Xmas weekend in El Calafate, where they took in the massive Perito Moreno Glacier ... a must-see when visiting the southern part of Argentina.

As we first reported ... Scarlett and Colin started dating back in June 2017 and things really heated up during a romantic dinner a couple weeks later.

Stefon Diggs won Son of the Year AND Brother of the Year awards in just a couple hours on Christmas ... 'cause the WR got his mom a new car and his bros diamond chains!!!

The Vikings superstar started his Santa impression Tuesday with a Mercedes ... delivering it to his mom on the holiday in a fashion she'll never forget.

"You get 1 mom... here’s something for the lady that put up with all my craziness. Merry Christmas everyone," Diggs wrote.

But, his bag of toys didn't end there ... the dude also had diamond shovels (get it, Diggs??) made by Al the Jeweler for his brothers!!!

It's a huge Christmas haul for the Diggs fam ... but don't worry -- we got a feeling this is a trend that'll continue for years -- Stefon just signed a 5-year, $72-MILLION deal!!

Eddie Murphy's family tree was on full display this Christmas ... and he looked like a proud papa right in the center of it.

The comedian was encircled by his 10 children Tuesday in a holiday family photo that included his fiancee, Paige Butcher, along with her mother and his mom, Lillian. The pic was shared on Instagram by his eldest daughter, Bria.

Eddie's smiling while holding his daughter he shares with Paige, Izzy Oona, while Paige introduces their newborn son, Max Charles, to the world. The boy was born November 30.

Murphy's other kids in the pic include his oldest son, Eric, whom he shares with Paulette McNeely, his son, Christian, whom he shares with Tamara Hood, his daughters, Bella Zahra, Zola Ivy, Shayne Audra and Bria and son Miles Mitchell ... he shares those 5 with ex-wife Nicole Mitchell Murphy.

And rounding it out, front and center, is his daughter, Angel Iris, whom he shares with Mel B.

The photo marks the first time Eddie's posed with all 10 of his kids. Bria captioned the pic, "Merry Christmas!!!"

He's already got the right beard, and on Christmas Eve ... James Harden went full Santa Claus and provided presents for families who could use an assist.

The NBA superstar partnered with Target and Karen Civil on Monday, letting 70 kids run wild in a Pearland, Texas store with loaded up gift cards for a personal shopping spree!

We're told each card had a couple hundred bucks on it, and the best part ... the kids had no idea they were in for this treat.

Donald and Melania Trump took a top secret sleigh ride overnight to Iraq to surprise the troops ... and wish them a Merry Christmas.

The 2 flew out of Washington late on Christmas and traveled overnight to the Al Asad Air Base west of Baghdad ... marking the President's first trip to see U.S. troops in a combat zone since his presidency began.

Trump's Press Secretary, Sarah Sanders, says POTUS and the First Lady are meeting with the troops and senior military leadership to thank them for "their service, their success, and their sacrifice."

The trip was reportedly kept under wraps for security reasons, and comes during tough times for the Prez in D.C. ... 5 days into the partial government shutdown.

There's also a NY Times report alleging Trump received his infamous bone spurs diagnosis to help avoid the Vietnam War draft from a foot doctor as a "favor" to his father, Fred Trump.

According to the report ... the daughters of the podiatrist claim their dad -- who rented his office from Fred -- performed the favor to get in good with his landlord.

Mark Wahlberg's beach bod is the gift that keeps on giving the whole year.

The "Instant Family" star is enjoying the holidays with his family in Barbados at the Sandy Lane Hotel, and hit the Caribbean sand Wednesday for some Boxing Day fun in the sun and a cool dip in the sea.

Mark's muscles are already an eye-catcher, but even more so when matched with his colorful trunks and cross necklace bling.

Drake's son has some creative talent, and the proud papa wants the world to see.

Drake posted this pic of his son Adonis' handiwork ... an abstract in blue, green, yellow and red paint with some telltale handprints!!!

The one-year-old's papa captioned the pic, "Adonis > Picasso don't @ me."

Drake became a first-time dad last year, confirming during the Summer he had a son on his album, "Scorpion" ... although pretty much everyone knew by then anyway.

Corinne Olympios spent Xmas day enjoying the Miami Beach sun with her boyfriend.

The former "Bachelor" and "Bachelor in Paradise" contestant was hanging with Jon Yunger. She's been seeing him since May.

This pool encounter turned out a lot better than a previous outing last year, when Corinne accused DeMario Jackson of sexually assaulting her on the set of "Bachelor in Paradise." She claimed she was super drunk and did not give consent to the sexual contact. The allegation brought filming of "BIP" to a halt.

An investigation -- which included video of the encounter -- concluded Corrine was a willing participant and there was no sexual assault. Filming resumed, but Corrine and DeMario were no longer on the show.

Demi Lovato was in the holiday spirit on Xmas day, celebrating with friends and family.

Demi looked relaxed and content as she snuggled with her dog. Demi had a special ornament made with the face of her dog, Buddy, who was killed in 2015 by a coyote.

She scored a few cool gifts for Xmas, including some Hermes mugs.

Grab your tissues ... this tearjerker's brought to you by Kansas City Royals prospect Brady Singer who surprised his parents with a VERY expensive gift that'll earn him an award for Son of the Year.

Singer posted this video on Christmas Day ... which begins with Singer's mom opening a red envelope. She starts reading Singer's heartfelt letter ... and if it doesn't give you all the feels, nothing else will. Singer's mom reads out loud: "I just wanna say thank you for everything you've done to help me reach my dreams ... Both of you constantly took off of work and spent every dime you made just to put a smile on my face."

Then ... her jaw drops. SINGER WIPED OUT THEIR ENTIRE DEBT!!!

Singer was selected by the Kansas City Royals with the 18th overall pick earlier this summer. He's a right-handed pitcher with huge potential ... which explains why the Royals paid him $4.25 million to sign with them instead of returning to Florida.

Another sign the Royals wanted Singer badly? They paid him well above the slot value of an 18th overall pick. Yeah, he's that good. And, he's a byproduct of his parents' hard work and sacrifices ... which is why Singer wanted to SHOCK them with an incredible gesture.

The Kardashians broke with tradition Monday ... their big Xmas Eve bash was not held at Kris' krib ... but it definitely did not disappoint.

The party went down at the Hidden Hills home of Kim and Kanye, and gotta say ... it was pretty spectacular. The main party area was kinda dream-like ... with fluffy clouds scattered about.

Kim and Kanye had a bunch of snow hauled in, so the kids could sled down a slope.

The guest list was impressive -- J Lo, Alex Rodriguez, Sia, Paris Hilton, Dave Chappelle, Kimora Lee Simmons and Tyler, the Creator.

And, get this ... the singer -- John Legend, who performed a bunch of songs off his Xmas album, "A Legendary Christmas."

Check out North planted on Kanye's shoulders as he dances to his buddy, John.

The Kardashians Xmas card this year is predominantly girls. It's pretty fitting that the matriarch of the predominantly female family was given a baller gift ... for Christmas, Kris got a custom-made Goyard suitcase, which runs upwards of $15k.

Just another fashionable reminder that they're rich as f***.

Donald Trump spread a little Christmas pain when he challenged a 7-year-old child who apparently dares to still believe in Santa Claus.

Trump and Melania fielded some NORAD calls on Xmas Eve, when the President asked the child if he still believes in Santa. It seems the kid said he did, and Trump responded, "At 7 it's marginal, right?"

Trump bitched the other day that he was sitting in the White House alone after the government shut down over the budget crisis. He had planned to spend the holiday at Mar-a-Lago.

Post Malone took advantage of some deep, deep discounts hours before Christmas Day ... hitting up a Target and getting some super sweet deals.

P.M. had his eyes on electronics at the Salt Lake City store ... just after 4 PM on Xmas Eve. He was there with a woman ... eyewitnesses say it's his GF.

Post was the beneficiary of the last-minute sales and plunked down more than $200 on stuff.

Joe Giudice's last Christmas in America is shaping up to be bittersweet, because it means he's just months away from being deported ... but he also gets to chow down on some fancy fowl.

TMZ's obtained prison menus from across the country, and locked-up celebs are being treated to some pretty decent Christmas cuisine ... including individual Cornish game hens for both Joe and DMX.

Guys like Bill Cosby and Suge Knight aren't so lucky, but will still get their fill of meat, potatoes and dessert. As for Mystikal ... well, his meal's not so merry. Here's a breakdown of their options:

Giudice at Pennsylvania's FCI Allenwood Low prison:

- Cornish game hen or broccoli quiche, cornbread dressing, whole kernel corn, baked sweet potato, chicken gravy, cranberry sauce, salad, dinner rolls and pie.
- Christmas Eve is a bit more downscale ... just chili and cornbread.

The 'Real Housewives of NJ' star is doing time for fraud and will be deported back to his native Italy when he's released in March.

DMX at West Virginia's Gilmer prison:

- Cornish game hen, deli sandwich, PB&J sandwich and chips. Inmates also get a $50 bump in commissary funds for December to use on chocolates, cookies and peanut cluster bars.

X is serving 12 months for tax evasion.

Cosby at Pennsylvania's SCI Phoenix:

- Roast beef, bean burger, whipped potatoes, gravy, green beans, creamy coleslaw, dinner rolls and baked fruit pie. Zero Jell-O.

Cosby got 3 to 10 years for sexual assault.

Suge Knight at California's Wasco State Prison:

- Turkey or chicken, gravy, stuffing, mashed potatoes, sweet potatoes, salad, veggies, cranberry sauce and ice cream.

Suge struck a plea deal in September in his murder case and started a 28-year sentence.

Mystikal at Louisiana's Caddo Correctional Center:

- 2 turkey dogs, potato salad, greens and cake. In other words, nothing special.

Diddy and his daughters posed for a super sweet pic, showing the strength of their family bond in the wake of the terrible tragedy that befell them.

Diddy and 12-year-old twins Jessie James and D'Lila Star mugged for the camera. Diddy's words ... "L O V E MERRY CHRISTMAS TO YOU AND YOURS."

TMZ broke the story ... the twins' mom, 47-year-old Kim Porter, died last month at her L.A. home. She had been battling the flu, although cause of death is still pending.
