The prankster just got pranked big time ... Jake Paul's fiancee made him believe she was pregnant, and his reaction was veeeerrrrry interesting.

Tana Mongeau -- a YouTube star in her own right, who just got engaged to Jake about a month ago -- pulled a masterclass prank on her soon-to-be hubby, telling him she was preggo ... and letting panic and chaos ensue. Gotta give it to her, she acted her ass off.

In the clip, Tana tells a seemingly unsuspecting Jake that she's gotta tell him something that he'll probably be mad about, which peaks his curiosity.

After a bit of back-and-forth, she finally comes out with it ... saying she's pregnant, and even showing him a bogus pregnancy test that reads positive. Then comes the difficult convo ... what to do about it now???

Check out the clip ... it seems like Jake would've actually been down to keep it, at least that seems to be his initial reaction. Gotta check with mom first though, of course.

What's also interesting is that Tana and Jake are a relatively newish couple -- having only been together for about two months prior to him popping the question in late June. She makes that much clear by what she tells him in this video too ... they haven't talked about a baby much, apparently.

Young viral love, nothing beats it.

'Spider-Man' star Tony Revolori channeled his movie character at Comic-Con, becoming the life of the party by climbing a tree with flash to spare ... and then getting booted right after.

Tony was at Entertainment Weekly's Comic-Con bash Saturday at the Hard Rock Hotel rooftop bar, Float, in San Diego -- this following an epic day of Marvel revelations, including casting announcements for "The Eternals," "Blade" and other projects. Big superhero day.

Eyewitnesses tell us he was hanging out with some actors from Amazon's new web series "The Boys" ... when a little game of truth-or-dare got underway.

We're told somebody dared Tony to climb a tree that was nearby, and without hesitation ... he hopped right up there and made his way across some branches. Classic Flash Thompson, right?

In video of the climb, obtained by TMZ, you can see a security guard rush over and tell him to get down. He wasn't very high up, but the guy looked kinda pissy about it.

Tony made his way down as more guards showed up -- and he got quite the ovation from onlookers, who told him the stunt was worth it. Tony seemed to agree.

It appears he was escorted off the property, because we're told Tony wasn't seen at the event afterward. Cops weren't called, so no harm, no foul. Flash left without incident.

Donald Trump made a surprise appearance at a wedding that had a theme -- Make America Great Again.

The wedding went down Saturday night at Trump National Golf Club Bedminster in Bedminster, New Jersey.

There was no doubt about it ... there were chants "USA, USA, USA," and "Trump, Trump, Trump."

You see the President kiss the bride and wave hello to the crowd that is cheering him on.  At various points during the evening, various people from the wedding party wore "MAGA" hats and even posed with Trump.

We're told the bride and groom -- PJ Mongelli and Nicole Marie -- are huge Trump fans. His Facebook is laced with Trump support, including a pic of him with the President.

The couple got engaged in 2017 at the Trump National Golf Club Bedminster.

Nicole Marie actually sent Trump multiple invites to the wedding, including a booklet that showcased encounters that she had with him, including rallies and Trump parties.

The live-action 'Lion King' reboot was swimming in money this weekend here in America -- making it one of the best openings ever ... this in spite of critics kind of sh***in' on it.

Jon Favreau's latest re-imagining -- he also did the live-action version of "The Jungle Book" in 2016 -- hauled in a monster box office number in the North American market over the past few days, making an estimated $185 million ... and soaring past expectations.

The huge payday launched 'Lion King' into the 9th slot for highest-grossing film ever (under "Avengers: Endgame," "Avatar," "Titanic," and other behemoths at the top) while also marking the largest July opening for a PG flick ever. In short, Disney made lots o' $$$$$$$$.

The funny thing is ... the movie is relatively so-so, according to critics anyway. It's got a 55% rating on Rotten Tomatoes and Megacritic -- which ain't good -- but folks still shelled out.

The biggest gripes about Disney's latest live-action revival is that the lions don't have any discernible facial expressions regardless of what's happening -- unlike the cartoon, which is very expressive throughout the roller coaster of events (RIP, Mufasa).

Not only that, but the biggest showstopping songs are a shell of themselves, and Beyonce barely gets any screen time -- yeah, we've seen it ... critics are sorta spot-on.

Cardi B's got Offset under her thumb leg -- and she proudly showed that off with a newly revealed tattoo while chatting with her hubby.

The rapper posted a very up-close and personal snapshot Sunday of what appears to be a Facetime convo she was having with Offset, in which she hoisted up her leg and showed him a tat bearing his name on the backside of her thigh. Awww? Sure, why not.

Cardi captioned her now-deleted post, "CAN'T WAIT TO GET HOME," throwing in a bunch of tongue emojis for good measure. She also put a tongue-out emoji over Offset's mug.

What's interesting about the tat is that it appears to have flown under the radar until now. We already knew Cardi was covered in ink (she's got upwards of 8 documented tattoos), but it's pretty sweet she's got her husband etched in too, considering their ups and downs.

Even more cool is the fact that Offset also has himself a 'Cardi' tat on his neck, under a pic of Buttercup from "The Powerpuff Girls." It made its debut early last year, and CB herself sure seemed to like it in a video she posted of the body art.

Looks like Cardi returned the favor between then and now. That's amore, alright.

'The Chi' star Sonja Sohn was arrested for cocaine possession ... TMZ has learned.

Sohn, who also starred in "The Wire," was arrested Sunday at 2 AM in North Carolina for cocaine possession, possession of marijuana and drug paraphernalia.

The paraphernalia charges are misdemeanors, but the cocaine charge is a felony.

Police tell us ... she was arrested and brought into the station at 2 AM and bailed out 6 minutes later.

She posted $1,500 bail and left the station.

She will be arraigned Tuesday.

Sonja played Detective Shakima Greggs on all 5 seasons of "The Wire." She plays Brandon's mom, Laverne, on "The Chi."

A$AP Rocky may actually be in even more peril as he lingers in a Swedish jail BECAUSE the U.S. government tried to help him.

The prosecutor has shown no sympathy for A$AP, despite the fact that the person he is accused of assaulting assaulted him first, and it's all on video. Nevertheless, sources connected with the case tell TMZ, the prosecutor has been immovable on the subject of release pending charges, despite the fact that the U.S. State Dept. and now the President of United States got involved.

As we reported, the State Dept. waged a full court press last Thursday, trying to get A$AP out of jail, to no avail. The prosecutor mistakenly played his hand Friday when he released a statement an indictment will be filed against Rocky. His office said it was a mistake to say that, but the intentions are clear.

Sources connected to the case actually think intervention by the State Dept. and the President -- who essentially said he would guarantee bail if they would release Rocky -- could actually BACKFIRE because they are trying to get in the prosecutor's business.

The Swedish Prime Minister as much as said so Saturday, after Trump got him on the horn and lobbied for A$AP's release, telling Trump about "the complete independence of the Swedish judicial system, prosecutors and courts." A spokesperson for the PM said, "He [the PM] underlined that in Sweden everyone is equal before the law and that the government cannot and will not attempt to influence the legal proceedings."

Translation ... butt out.

Soulja Boy is making some huge changes to his lifestyle following a stint in county jail ... and that means shrinking his social circle and shying away from social media.

Sources close to Soulja tell TMZ ... his three months in L.A. County Jail served as an eye-opener, and now that he's back home, he's cutting people off and cutting off his time on Twitter and Instagram.

The biggest change ... we're told Soulja kicked a bunch of people out of his crib in the San Fernando Valley, the same home that was burglarized when he was locked up.

TMZ broke the story ... crooks hit Soulja's home and made off with $500,000 in cash, jewelry and his iPhone -- which the alleged thieves used to go live on Soulja's IG account -- and when SB caught wind of the burglary in jail, he was convinced it was an inside job.

Soulja's inactivity on social media is also related to the burglary ... we're told he's still upset about it, and he just wants to keep to himself and stay away from the masses.

As we first reported ... Soulja was sprung from jail last Sunday, getting out 146 days early due to a combo of good behavior, time served and overcrowding. Back in April, SB was sentenced to 240 days and 265 days of community service for violating his probation.

Pablo Escobar's bro wants to squash his "flamethrower" beef with Elon Musk ... by proposing they go into business together, but only if Elon can convince Prez Trump to issue a pardon.

Yeah, things just got weird.

The Colombian kingpin's bro, Roberto, fired off a letter to Elon -- or as Roberto calls him, "smart gringo" -- to offer several ways they can put their bad blood behind them. As we first reported ... Roberto claims Elon's The Boring Company committed intellectual property theft when one of its engineers jacked the idea of making a toy flamethrower.

Roberto starts the letter -- obtained by TMZ -- by giving Elon a nickname ... La Mosca (The Fly). Read the letter ... Roberto explains why he gave him the nickname. What's more ... one of Roberto's proposed solutions is to get Elon to speak to Trump and pardon him ... so they can build the company "Escobar Musk Enterprises." No joke.

Roberto's second solution ... roll up their sleeves and start a weed biz!!! Seriously ... Roberto's even got a company name picked. Roberto also offers a third solution ... if ya wanna call it that.

NBA star Trae Young says the hype about LaMelo Ball is REAL -- because he believes it's entirely possible the youngest Ball bro ends up a top 3 NBA draft pick in 2020.

The Atlanta Hawks star just came off a FANTASTIC rookie season, and has been working out with LaMelo while he's out here in Los Angeles.

So, when we saw Trae in BH (#shopping) we wanted to know if he thinks Ball has the goods to be a top three pick in the NBA draft when he's eligible next year.

"Possibly, yeah for sure. He'll be ready the by the time he gets to the league."

Young didn't stop there, telling us it really doesn't matter where Ball is drafted, because no matter where it is he's gonna be a dope NBA player.

"He'll be good in the league. If he's #1, #2, #3 ... regardless he'll be a good player."

Ball is a mystery in basketball circles -- he's 6'7" with real playmaking ability ... but his bizarre basketball journey (remember Lithuania?) is making some scouts think twice.

We'll see what happens, but at the very least we know 'Melo seems to have Trae's vote.

The man who voiced the prince in "The Little Mermaid" says the guy expected to land the role in the live-action remake is a perfect fit ... and the new Ariel's a home run.

Christopher Daniel Barnes -- who voiced Prince Eric in the 1989 classic -- tells TMZ ... Harry Styles would be an excellent choice, because he actually checks all the boxes of a Disney prince in real life.

Styles is reportedly the front-runner for Eric, and Barnes says it's an added bonus he can sing ... now that some songs have actually been added for him.

Because, fun fact -- Barnes didn't get to sing any catchy tunes in 'Little Mermaid' ... and says he's the only Disney prince with that distinction.

Gilbert Arenas was NOT the problem in a crazy car crash earlier this month that wrecked his Maybach and caused another car to FLIP OVER ... TMZ Sports has learned.

Arenas was involved in a terrifying accident back on July 7, when a 2000 Toyota RAV4 collided with his 2018 Mercedes on the 101 freeway in Encino, California.

But, the California Highway Patrol tells us a 27-year-old man, who was the driver of the Toyota, was actually at fault for the car crash ... 'cause the CHP says he was speeding when he hit the NBA superstar.

Fortunately for everyone involved, the CHP says the man only suffered minor injuries ... while 37-year-old Arenas was not hurt at all.

But, seriously, it's crazy no one was hurt ... we obtained 911 calls from the scene -- and they paint a picture of a wild accident.

We're told no arrests or citations were issued in the incident ... and it's unclear what the cost of all the damages were.

Matthew Broderick is the king of good looks!

Here is the 21-year-old version of the 'Ferris Bueller's Day Off' lead actor looking fresh-faced at an event in New York City back in 1983 (left).

And 36 years later... the now 57-year-old voice actor for the iconic Disney role of Simba in the 1994 animated film 'The Lion King' -- the role is reprised by Donald Glover in the new live action movie hitting theaters this weekend -- sporting some specks at a screening last week (right).

Well, looks like that is just the circle of life!

The question is ...
