Elon Musk and Amber Heard strapped up and held on tight ... for a little semi-extreme fun in Australia.

The couple went ziplining in the Currumbin Wildlife Sanctuary on the Gold Coast. The actress and Tesla honcho had a lot on the line here, and not just because he was trusting his multi-billion dollar ass to a safety harness.

Two of Elon's 5 sons came along, so Amber had the added pressure of being dad's cool gf. She probably scored some bonus points, since she's Down Under to shoot "Aquaman" with Jason Momoa.

Looks like the couple -- coming up on 1 year together -- had a good time. Still, we gotta say ... no one, not even Elon with his riches, looks good in those helmets.

Prince William might be royalty, but he's not above a good squirt in the face ... especially when he's on the front lines of a marathon handing out H2O.

William and Kate were at the London Marathon Sunday, being good citizens and handing out water to runners -- and this is the thanks they got.

At least the unknown practical joker had the decency to avoid the Duchess's mug.

We're guessing Will was a good sport about it. He's been known to be a happy-go-lucky future king from time to time.

Jennifer Meyer's 40th birthday party turned into THE non-Coachella celeb event of the weekend ... with Jennifer Aniston, Courteney Cox, Katy Perry ... AND Orlando Bloom all showing up.

The huge bash went down at Peppermint in WeHo, where Justin Theroux was hanging with the wife and her "Friends" pal. Jessica Alba, Nicole Richie and a bunch of other celebs were inside.

As for Katy and Orlando ... no word if they saw each other inside, but there was at least a chance.

Jewelry designer Meyer and Tobey Maguire split up last year. Kinda obvious now who got the bulk of their famous pals in the breakup.

At least he's got Leo DiCaprio.

Bill O'Reilly's second day of unemployment, and he's already bargain hunting ... with $25 mil falling out of his wallet.

The ousted FOX News anchor hit up Eric Comfort Shoes on Long Island, where he was lucky enough to come across a big sale. Of course, Bill could really be looking to buy the whole damn store.

He's leaving his longtime gig with a reported $25 million payout -- the equivalent of about a year's salary for O'Reilly.

No spin? He won't be hurting for money.

Cuba Gooding Jr. coped with the pain of his dad's death by working on his movie with Jaden Smith.

They were in Toronto shooting Friday morning -- the day after Cuba Gooding Sr. passed away. Focusing on his work seemed to do Cuba some good as he managed a few smiles with Jaden between scenes.

His father -- 72-year-old Cuba Gooding Sr. -- was found dead in his car Thursday.

Cuba Jr. powered through a long day of filming "Life in a Year" when he got the news Thursday evening, but the emotion showed on his face.

Tyga has the perfect way to get over Kylie Jenner ... just find a new model.

He did dinner with a mystery brunette at Serafina Sunset in WeHo Thursday evening, and the attraction was obvious. Not only was Tyga staring her down like she was dessert -- and maybe she was -- the chick looks very familiar.

Young, busty, shoulder-length dark hair with a love for skin tight jeans -- and best of all -- loves to rock crop tops.

Richard Simmons was playing with the paparazzi Thursday, with a lot of help from the LAPD.

TMZ broke the story, Simmons returned home after spending 3 days in the hospital for gastrointestinal issues.

As Richard sat in his garage waiting for cops, a photog got a pic that partially shows his face, which we haven't seen in 3 years ... except for one Bigfoot-like image last summer.

Sources who have been around Richard all tell us he's fine ... he's got a bum knee and often walks with a cane but mentally he's "all there" and is just sick of maintaining the "Richard Simmons persona."

So Thursday late afternoon ... Richard was returning home, didn't want to be seen and knew paparazzi were at his gate. So he and his housekeeper called the LAPD and apparently made things sound urgent enough that at least 4 cops showed up and ended up forming a human shield, allowing a blanket-covered Simmons to slink into his home without anyone snapping his mug.

Cuba Gooding Jr. showed his emotions on his face Thursday after learning his father had died.

TMZ broke the story ... Cuba Gooding Sr. was found dead Thursday in the San Fernando Valley ... slumped over in his car. Cops found alcohol and drug paraphernalia and believe he OD'd.

Cuba Jr. was filming "A Life in a Year" in Toronto, Canada when he learned his 72-year-old father had passed.

The photog who took the pics says Jaden Smith, who is co-starring in the movie, was comforting Cuba.

Richard Simmons just came home from the hospital ... with a little help from the LAPD, and under the cover of a blanket.

Simmons checked himself in on Monday for gastrointestinal issues. He returned home Thursday afternoon ... but there was a problem. Simmons longtime housekeeper called the LAPD and said she was followed by paparazzi, and ended up driving into the garage and hiding because she believed they might be on her property.

Cops arrived and found Richard and the housekeeper inside the garage in his Range Rover. They formed something of a human shield -- and Richard threw a blanket over his head -- and went inside the house.

Eva Longoria does the opposite of take it easy on a Hawaiian vacation ... she prefers screaming "Geronimo" from the highest cliff!!!

Eva's on vacation, island hopping with hubby José Bastón, where she was very clearly in full activity mode ... jumping in waterfalls in Oahu one day, then jumping on a paddleboard in Maui on another.

She did sneak in a kiss or 2 along the way, but you can tell paddling was still at the forefront of her mind.

Jason Momoa is Aquaman on and off set because even when he's chilling shirtless he looks like a freakin' superhero!

Momoa showed off his bulging pecs, bis, abs -- everything really -- while hanging on Australia's Gold Coast. We'd say he shamed the mere mortals around him, except his friend is a beast too!

"Aquaman" doesn't start shooting until the end of May, but Jason looks ready to go right now. Dude's even got his body double ready to roll.

Bill O'Reilly had what turned out to be an 11th hour meeting with Pope Francis -- but even shaking hands with His Holiness wasn't enough to spare his gig at FOX News.

Bill was in St. Peter's Square Wednesday morning -- he'd been on vacation -- when he got an audience with the Pontiff. Just a quick meet and greet really ... handshake, exchange of salutations.

But put yourself in Bill's shoes at the time -- wouldn't ya have to ask for a prayer or two?

As we reported ... FOX News announced O'Reilly would not return to the network after about 70 advertisers pulled out amid allegations of sexual harassment against him.

Kim Kardashian made a joke about the flu helping her drop some poundage ... but these pics prove a little temp can do a body good.

Paps got Kim out and about in L.A. Tuesday night in a bralette, skin-tight pants and a very loose coat that let everything hang out. She looks good ... damn good.

That same night, Kim tweeted that she was 6 pounds down from the flu ... joking it made for an "amazing" diet. She took heat ... and then took the tweet down.

All Mariah Carey needs is a Santa outfit, 'cause she's got the GIANT sack o' toys down pat ... even in April.

Mimi was out Tuesday with her twins putting a dent (small ding, really) in her pocket with a shopping spree at Tom's Toys in Bev Hills. Moroccan and Monroe get the fun ... mommy's bodyguards get the heavy lifting.

Mariah was in a giving mood -- a few hours later she was at Catch giving her manager, Stella Bulochnikov ... a $30k Louis Vuitton trunk!

Get this woman a Santa suit, stat! Low cut, of course.

Lady Gaga and Bradley Cooper shared a passionate and long kiss at a gas station ... for a movie, of course.

Gaga's making her big screen acting debut in the remake of "A Star is Born." She'll be playing alongside Cooper, who's also making his directorial debut.

The duo shot a sexy scene Monday in the California desert, where they will also film scenes on the Coachella grounds during the week ... which is super convenient for Lady Gaga, who headlines again this coming weekend.

La La Anthony is making a big statement in NYC -- going out without her wedding ring ... after separating from her husband, Carmelo Anthony.

Sources connected to La La tell us she hasn't worn the ring in more than a week -- since she moved out from the home she shared with the NBA star.

We broke the story, La La ain't happy with Melo after a woman came forward claiming to be 6 months pregnant with his kid.

So far, no divorce papers have been filed but sources tell us it's just a matter of time at this point.
