Tony Hawk Xtreme Fiji Vacay ... Before Xmas

Screw decking the halls ... Tony Hawk's hitting the Fiji islands as an early Christmas gift to the Hawk clan -- and it looks siiick.

No sign of Tony shreddin' on land ... but the pro skater's 3 younger kids -- Spencer, Keegan, and Kadence -- are keepin' it extreme in the water with surfing and cliff diving.

The Hawks are chillin' out a little too ... and why not? They got a damn infinity pool AND oceanside fine dining.

Drink up, Tony -- you're winning winter break.

Amber Heard & Elon Musk The Smooch that Sealed It ... Again

10:00 AM PT -- A source close to Elon tells TMZ, "Amber invited Elon to her favorite restaurant for lunch, which serves cuisine from her home town of Austin. They caught up and kissed goodbye, but are not back together."

Amber Heard and Elon Musk wasted no time re-igniting an old flame ... marking their territory with a kiss.

The actress and the genius behind Tesla and SpaceX grabbed lunch Thursday in L.A. and, just before hopping in separate cars, Elon reached behind Amber and planted a smacker.

The PDA-heavy lunch comes about a month after TMZ broke the story ... Amber and Elon were together for the first time since announcing their breakup in August.

The timing of that reunion was revealing ... one day after Rolling Stone posted an Elon profile in which he said how heartbroken he was about breaking up with Amber. He told the mag, "I was really in love, and it hurt bad."

Shawn Mendes & Hailey Baldwin Packin' On the PDA

Shawn Mendes and Hailey Baldwin didn't need mistletoe Thursday as they strolled to the Toronto Christmas Market.

The freshly-minted couple are in Mendes' hometown for the holidays. The day before they hit up Daniel Caesar's concert.

Hailey's been linked to Bieber, Drake, Cameron Dallas ... but, times and seasons change ... and now it's all about Shawn.

Hailey's been mum about Justin's blowup with Selena ... as we reported Selena was furious Justin contacted Hailey to make amends over their breakup, and it landed them in couples therapy.

Baldwin's clearly a bit distracted.

SKIMPY SANTA MOVES

Sofia Richie got down and dirty -- sexy dancing for boyfriend Scott Disick -- and it was all while her dad's music blasted in the background.

Disick shared the clip of a 19-year-old Richie in some skimpy Santa gear moving her hips and shaking her ass in his kitchen. It's a whole lotta awkward, considering the song she's gyrating to is Lionel's "All Night Long."

34-year-old Scott has been seemingly settled down since getting with Richie months ago ... looks like their recipe for fun is some one-on-one dance parties.

Jay-Z Show in L.A. Draws Tons of Celebrities

Jay-Z might have 99 problems, but getting famous fans to attend his concert ain't one.

Hova's 4:44 tour made its way to The Forum Thursday night in Inglewood where there was no shortage of celebs. Queen Latifah, James Franco and Charlotte McKinney are some of the actors/models who carved out time to take in the show.

The list didn't end there ... French Montana, G-Eazy and Big Sean are among the rap game's biggest names who also paid their respect for Mr. Carter.

Diplo Delivers Surprise Beats for Charity Helps Raise $60k

Diplo typically earns big money for his DJ sets, but Wednesday night he helped raise cash at a mini festival ... with Rosario Dawson and Eric Andre watching.

The Mad Decent label head wasn't even on the flyer for the 2nd annual 'LA Gives Back' concert, but surprised the 2,300 fans who packed Union nightclub. Other DJs like Ookay, Valentino Khan, and Ghastly pumped up the crowd from the venue's 5 stages.

We're told Rosario and Eric were in the crowd. Unclear if it was a date, since they reportedly broke up 3 weeks ago. We know they helped the fundraising effort by hitting up the merch booth.

The event raised $60k to help 2 L.A. shelters -- My Friend's Place and the Downtown Women's Center.

Ashley Graham Bustin' Her Humps in Morocco With the Help of a Camel

The desert is usually hot, but Ashley Graham made it extra hot modeling a bunch of bikinis in the sand in Morocco.

Graham shared several behind-the-scenes pics from her photo shoot Thursday in Taghazout. How behind? There's even a photo of her inside her makeshift changing room with nothing on.

Ashley's a pro, but she still got an assist from a camel on the shoot. Doesn't seem like she was into the humped animal, not that she needs any help in that department.

Enrique & Anna $600k Miami Crib Makeover ... Bring on the Twins!!!

New parents Enrique Iglesias and Anna Kournikova are going all Donald Trump to make their Miami mansion a fortress of privacy for their twins.

We broke the story ... Anna gave birth to the twins, a boy and a girl, and while she was secretly pregnant, the couple started building a huge 16-foot-tall wall around their Miami home. Construction started in late summer, deep into Anna's 2nd trimester.

According to city building permits, they're also adding a 2-story single family residence to their property -- along with baby-proofing measures, like a "child barrier for pools."

The wall makes sense. Privacy is totally Enrique and Anna's M.O. -- since they clearly went though a whole pregnancy without anyone ever knowing.

The docs say the home makeover will cost $600k when it's all said and done.

Phaedra Parks Selling Atlanta Crib for $1.195 Million

Phaedra Parks is having a good ole fashioned French provincial sale ... which has less to do with 18th Century Paree, than it does 21st Century ATL.

"The Real Housewives of Atlanta" star's unloading her 4 bedroom, 6 bath home which she bough in 2013 for $845k. Phaedra could be turning a nice profit since she's listed it for $1.195 million.

That's the bargain price, too -- she initially put it on the market in July for $1.499 mil.

The pad has a pool, nice yard and a sweet covered patio area for chilling through hot ATL summers. As for why Phaedra's bolting -- we're told she has another home in Atlanta.

So, this beautiful spread was just her backup. Nice.
