3 of the 4 suspects in XXXTentacion's murder knew each other and enjoyed flaunting their money together before the rapper was killed ... because there's video proof.

Dedrick Williams, Robert Allen and Trayvon Newsome -- who've all been indicted by a grand jury for first degree murder -- were in an Instagram vid posted by Williams weeks before X was shot to death in S. Florida ... trying to look poppin' while sifting through stacks of big bills.

The fourth murder suspect and alleged gunman, Michael Boatwright, is not seen in the vid.

As we've reported ... Williams and Boatwright have been arrested, but Newsome and Allen are still wanted. Police believe Newsome is a second trigger man.

It's been more than a month since XXXTentacion was gunned down outside of a motorcycle shop in Pompano Beach.

The good news for War Machine is that he found love and he's now engaged to 30-year-old Ashley Farrington ... bad news is there's no conjugal visits in the state where he's locked up. Congrats?

Family sources close to Ashley tell TMZ ... War Marchine -- who is serving a life sentence with a possibility of parole when he's 71 -- first got acquainted with Ashley when she started writing to him as his pen pal last summer. We're told the relationship evolved to visits to Ely State Prison. They posed for this pic a few weeks ago.

Feelings developed and, earlier this year, the 36-year-old former UFC star wrote a poem asking for her hand in marriage. She said yes, even though he was sans ring. 

War and Ashley can have a wedding ceremony in prison and share a hug, but that's all the physical contact they'll have for a very long time -- Nevada doesn't allow conjugal visits. So much for consummating the marriage. 

As we reported ... War was found guilty of sexual assault, coercion, battery by strangulation, kidnapping and several other charges after attacking his ex, porn star Christy Mack.

We've reached out to War's attorney, who would not confirm nor deny the engagement.

A creepy Charles Manson painting made with the artist's blood is awaiting an even creepier finishing touch -- the cremated remains of Manson himself -- and then it can be yours.

Artist Ryan Gillikin tells TMZ ... he created this painting using his own blood, and was able to obtain some of Manson's ashes from someone who attended the spreading of them ... back in March, near Porterville, CA. 

Gillikin plans to use the ashes to fill in Manson's eyes in the painting, and then it will be complete.

Gillikin and his ash-grabbing biz partner plan to auction off his masterpiece and use the proceeds to make a monument for Steven Parent ... one of the victims of the Manson Family murders.

We'd say buyer beware, but this seems more like a beware of buyer situation.

Post Malone would gladly offer his services -- FOR FREE!! -- to perform at his buddy Justin Bieber's wedding ... but if they need a flower boy, he's game too.

We got the rapper leaving a restaurant in WeHo Thursday afternoon and the guy couldn't be happier for the Biebs and Hailey Baldwin. TMZ broke the story ... Justin proposed to Hailey earlier this month while on vacay in the Bahamas.

Post is so happy for the Biebs ... he lobs compliments at his boy even while he's getting swarmed by fans. Watch.

Before this stylish young man was tied up solving crimes on television, he was just another well-dressed boy in a bow tie growing up in Margate, FL. Can you guess who he is?

Judge Jeanine Pirro doesn't say she regrets going on "The View" -- even though it ended in a shouting match -- but it doesn't seem like she's in a hurry to go back either.

We got the Fox News star in NYC Thursday and asked about her highly contentious appearance on the talk show earlier in the day, which got especially heated with Whoopi Goldberg.

Jeanine tells us she can handle debating people with opposing views -- even if she's outnumbered ... but says she's got a big problem with getting an invite to talk and then being treated like garbage. 

As for Whoopi, the judge doesn't have much more to say other than what was said during their showdown and, as she points out ... it probably wouldn't resolve much anyway.

Now get out of the way ... Jeanine's got places to be.

The folks who produce 'Teen Mom' know what sells ... because TMZ has learned Bristol Palin is joining "Teen Mom OG."

Production sources tell us, Sarah Palin's daughter has signed on as a regular on the show. It appears she's helping to fill the void left by another famous cast member -- Farrah Abraham -- who was fired for being way too difficult. She disputes that, and says she got the axe because she was a porn star.

As you know, Bristol -- now 27 -- has 3 kids and was famously engaged to Levi Johnston. She eventually married Dakota Meyer, whom she's in the process of divorcing. She was 17 when her first kid, Tripp, was born.

Bristol will join cast members Amber Portwood, McKenzie McKee, Maci Bookout and Catelynn Lowell.

The season fires up on MTV this Fall. 

Asia Argento's still grieving the loss of Anthony Bourdain.

The actress shared a personal photo Thursday of herself with her late boyfriend ... the 2 are in a red convertible looking happy, with the 'Parts Unknown' host smirking while holding a green umbrella over them.

“Nessun maggior dolore che ricordarsi del tempo felice ne la miseria; e ciò sa 'l tuo dottore. Ma s'a conoscer la prima radice del nostro amor tu hai cotanto affetto, dirò come colui che piange e dice.” Dante Alighieri, Divina Commedia, V canto #Inferno May 27th 2018

A post shared by asiaargento (@asiaargento) on Jul 19, 2018 at 9:34am PDT

Asia captioned the pic with an Italian poem from Dante's "Divine Comedy," which translates to ... "There is no greater sorrow than to be mindful of the happy time in misery, and that thy Teacher knows. But, if to recognize the earliest root of love in us thou hast so great desire, I will do even as he who weeps and speaks."

According to the post, the photo was taken May 27 ... just a little over a week before Bourdain died by suicide. As we reported ... he was found dead in his French hotel room after using the belt from his robe to hang himself.

Argento wrote after his death that she was "beyond devastated." She's shared a few photos with Bourdain since then ... clearly trying to take Dante's words to heart.

Congressman Matt Gaetz didn't fall for Sacha Baron Cohen's trap to promote putting guns in the hands of toddlers, but admits he was clueless about who he was talking to.

We got the Florida Representative Thursday at Reagan National Airport, and asked how he managed to avoid being duped like several of his Republican peers ... who shockingly read a fake PSA calling for school children to be armed.

Gaetz says he'll never let a teleprompter do him in.

DUI Matt Gaetz supports arming toddlers w/ firearms?

Gaetz tells us he's still disappointed in himself for not recognizing Cohen in makeup, because he missed a chance to whip out his own Borat impressions to the man himself.

He also has some advice for folks, like Sarah Palin, who are complaining about getting played.

The Congressman didn't elaborate on his anxiety about teleprompters, but since he loves Borat, we're gonna guess he's also seen Ron Burgundy's work.

Police have now named the 2 gunmen they believe killed XXXTentacion, and a grand jury has indicted the alleged gunmen and 2 others for first degree murder.

The Broward County Sheriff's Dept. says Michael Boatwright -- arrested earlier this month -- and Trayvon Newsome were the trigger men in XXX's murder. Newsome is still wanted. The other 2 indicted suspects are Dedrick Williams and Robert Allen.

As we reported, Dedrick was the first taken into custody ... while Allen is still on the lam. In addition to murder, all 4 men were also charged with armed robbery with a firearm.

It's been almost exactly one month since the rapper was gunned down in Pompano Beach, FL.

G-Eazy has NOT jumped to dating Demi Lovato after his split from Halsey ... and that's coming straight from his ex, Halsey.

We got her Thursday at LAX, and had to ask her about the speculation G's hooking up with Demi. There were reports they hit up a Hollywood club last weekend. Even though that turned out to be false ... the rumor's taken off.

Halsey, who announced the breakup from G-Eazy earlier this month, says NO CHANCE. He denied the Demi buzz at the ESPYs, and his ex is fully backing him.

As for ever reuniting with G-Eazy -- Halsey has a strong take on that.
