Travis Barker has good reason to be worried about a run-in with Shanna Moakler's biker boyfriend ... turns out he's a Hells Angel.

TMZ has learned the boyfriend Moakler allegedly threatened to let loose on Barker ... is in the club's San Fernando Valley Chapter. Shanna and Travis were both arrested a couple of weeks ago for slinging death threats.

Sources close to Shanna believe Barker will try to use her bf's Angel ties against her in their custody battle, but we're told Shanna's insisting he's a nonviolent pussy cat with no rap sheet.

Despite her concerns ... Shanna posts pics of her man on the reg, but always blurs the Hells Angel patches on his cut. We're told Shanna's reminding friends the Angels do a lot of good charity rides and fundraisers.

Just don't ever touch his hog ... unless you're Shanna.

Reconciliation is probably off the table for Slash ... 'cause less than one month after calling off his marriage, the rocker got matching tats with his new GF ... and then MOVED IN with her.

TMZ has learned ... the 49-year-old decided to prove his commitment to Meegan Hodges by permanently marking their bodies with a matching set of GPS coordinates.

And if the tats weren't proof enough of a serious relationship -- we've also learned they've moved into a house together in the deep part of the San Fernando Valley ... with Meegan's two teenage daughters.

As for the home, it's nice ... 3,120 square feet, 5 bedrooms, 5 baths, a pool and a rooftop deck -- and we're told Slash is leasing it.

As we previously reported, Slash filed for divorce from Perla Ferrar on December 30th after 13 years of marriage. They have two kids of their own.

So far, no comment from Perla ... but we're guessing she probably won't be sending a housewarming gift.

Justin Bieber is not shtupping the young women everyone thinks he's shtupping.

Hailey Baldwin and Kendall Jenner have been hanging with Biebs for a while now, and on the surface it looked like the chumminess was more than friendship. Turns out that's all it is.

As we reported, Bieber has been changing things up ... he hasn't been in trouble for months, he's not hanging with his old crowd and he's spending a lot of time on self-improvement.

Our Bieber sources say J.B. likes hanging with Hailey and Kendall because they're relatively drama free and positive. They go to church, restaurants, concerts and clubs, but it's not romantic.

The trio went to the Clippers game Thursday night, along with 3 Vine stars -- King Bach, Curtis Lepore and Nash Grier.

The trio went to see Bieber's pastor Judah Smith speak on Wednesday night and they hit up a comedy club afterward.

We're told Bieber's not with Selena either -- they see each other, but they're not a couple. Fact is ... he's single, and pretty happy.

She loves me, she loves me not.
She loves me, she loves me not.
She loves me, she loves me not.
She loves me, she loves me not.
She loves me, she loves me not.

Justin Bieber and Selena Gomez had dinner Thursday at Mastro's Steakhouse in Bev Hills. Diners and staff saw them holding hands during their dinner.

If JFK is watching ... here's your New Frontier ... two of your niece's children are banging the offspring of the dude who sang "Achy Breaky Heart."

We've learned Miley Cyrus is not the only one getting a piece of the Kennedys ... her brother Braison is dating boyfriend Patrick Schwarzenegger's sis, Christina.

Miley and Patrick have been tight since November. We now know a month later 20-year-old Braison began hooking up with 23-year-old Christina.

So here's the conundrum ... if both couples get married, Braison will be Miley's brother-in-law and brother, while Christina will be Patrick's sister-in-law and sister.

Camelot meets PBR ... awesome.

Two women got into a knock-down, drag-out fight over a big male star ... and if we asked you to guess who the male star was ... how many guesses would you need to get to David Cassidy?

Alas, that's exactly what happened back in September (sorry, our David Cassidy sources are slow) in Boca Raton, FL ... and it ended with cops and doctors.

According to police ... when they showed up, they found one of the women, Maura Rossi, with a bloody nose, trying to leave the scene. Rossi told police she tracked her boyfriend, Cassidy, to another woman's house using the "Find My Phone" feature on the iPhone.

Both Rossi and the other woman, Georgina Zahran, had the same story ... Rossi knocked on the door, they argued and eventually came to blows. Zahran had blood on her face and a few cuts and bruises from the dustup.

The women eventually talked it out and neither was arrested ... though Rossi did get taken to the hospital.

David is still with Rossi.

In the end, it seems like David said "I think I love you" one too many times.

Nicki Minaj and Safaree Samuels each went out of their way Wednesday night to send clear signals to the other and the world ... they're with other people now.

First you had Safaree, who went to Boa with his new chick, a model named Candice Brook. As if Boa wasn't already a place to be seen ... Safaree pulled up in a ridiculous red car.

Then we have Nicki ... who popped up in a selfie with Meek Mill ... whom Nicki has been linked to for months, but she never owned it until now.

Messages received.

"Modern Family" star Sofia Vergara is engaged to marry one of the hottest guys in town ... so why is she hiding her massive engagement ring?

"True Blood" star Joe Manganiello popped the question over the holiday weekend after just six months of dating (and Sofia only broke up with her other fiancé less than two months before that).

Vergara was spotted at the airport with her ring turned around so nobody could see it.

The ring is rumored to be at least 10 carats ... who's gonna miss it?

The daughter of Sacramento Kings owner Vivek Ranadivé tells TMZ Sports ... yes she's tight with Tyga -- but there's absolutely ZERO boot-knockin' going down between them.

As we previously reported, Tyga has been spending a LOT of quality time with Anjali Ranadivé (aka Anjali World) ... who happens to be an aspiring singer. The two were seen getting off a private jet together earlier this month leading to speculation they were romantically involved.

But Anjali tells us, "We're just friends and working on music together."

We're told the two met through her manager ... and Anjali says they hit it off (in a platonic and professional way) -- and have been hitting the studio together ever since.

They've already recorded one song together which they performed at a recent Kings game (see video below.)

"I look up to him musically," Anjali says ... "and I can't wait to make even more music with Tyga in the future."

Like a cheesy holiday romantic comedy ... Chris Brown and Karrueche Tran flipped their relationship back to "on" -- all because of a run-in on the eve of Christmas Eve.

Sources close to the couple tell us Chris had been trying to reconnect with Karrueche following their nasty public break-up ... but KT wasn't having it until Tuesday night at Playhouse.

We're told they chatted politely inside the nightclub until Chris asked her to go somewhere more private to talk about giving the couples thing another shot.

Karrueche agreed ... and we actually shot them on the way out of the club to go have that convo.

The final nail in the coffin came Thursday when they went to Sean Kingston's "Christmas with the Kingston's" party -- together. Based on this photo ... the talk went well. Again.

Chris Brown may be out of the dog house with Karrueche Tran ... but now he's stuck dragging her new pooch everywhere -- meaning he's officially back to boyfriend duties.

The on-again/off-again couple hit up Nike Town in Beverly Hills on Friday while parading the dog Chris apparently bought her for Christmas -- but did not flash any new rocks.

Remember, on Christmas Karrueche posted what looked like an engagement ring -- but that's highly unlikely since it was on the wrong hand in the Insta pic (which she's now deleted)-- AND she didn't flaunt it for cameras yesterday.

So, the only remaining question -- who picks up the poop?

Chris Brown has gone from venomously putting Karrueche Tran on blast ... to giving her what looks like a small diamond mine.

Karrueche coyly posted the pic of her latest acquisitions ... courtesy of CB.

She's not saying if either is an engagement ring, but it's doubtful given that it's on the wrong hand.

It's certainly a major about face ... we spotted them the other night leaving Playhouse nightclub in Hollywood, the first time they've been publicly seen since their nuclear breakup.

Looks like he also gave her a pooch.

Chris Brown and Karrueche Tran loved, hated, loved, hated ... and apparently the pendulum has
swung again.

We got video of the feuding exes leaving Playhouse early Wednesday morning. The two of them walk out of the club together, but appear to leave separately.

Karrueche was hosting a holiday party and toy drive at the club and there were flyers with her mug promoting the vent, so it's not like Chris didn't know she was there.

It actually seemed like this was a split for good, after CB went on stage and screamed "F*** Karrueche!"

Will this be the final chapter? Not a chance.

The ex-boyfriend of Nicki Minaj is taking their break-up INCREDIBLY hard ... to the point he's having suicidal thoughts.

Safaree Samuels is confiding in friends that he's an emotional wreck over his breakup with Nicki after a 12-year relationship. He's become a shut-in, spends days and nights smoking weed, and has talked openly about suicide.

Safaree is telling friends he won't get in touch with Nicki because she's now hooked up with Meek Mill. He says it's torture for him, because he believes Meek Mill destroyed his relationship with Nicki over false claims he cheated.

Safaree's friends say they're scared these are more than idle threats. They've urged him to see a shrink. The problem ... he's seeing one whom he says has been giving him meds that make him even more emotional.

Ray J's ex-girlfriend who threatened suicide Wednesday was pushed over the edge after she found out Ray was nuzzling up to the modern day Helen of Troy ... Karrueche Tran.

Cops were called after Princess Love called Ray and threatened to shoot herself. A short time later she called him back and said she would not go through with it.

As we reported ... Ray broke up with Princess Love Tuesday night after a big fight. Now we know where he went afterward.

Ray went to a studio to shoot a New Year's Eve special for BET. Karrueche was also on the show and Ray hung out with her until 4 AM. We got a couple of pics which show they were definitely getting along.

Unclear if there's a relationship, but it's definitely a good start.

Looks like Ray J's doing some damage control ... he posted a pic with Princess Love late Wednesday night with a very poor choice of words in the caption.

Notre Dame WR Justin Brent -- the guy who dated porn star Lisa Ann -- has moved on to thicker pastures ... and is now dating one of the most famous booty models in the ass game ... TMZ Sports has learned.

Of course, Brent's brief relationship with the 42-year-old porn Hall of Famer made national headlines earlier this year ... since the 19-year-old goes to a Catholic university which frowns upon pre-marital sex.

But now it seems Lisa Ann is out ... replaced by Elke the Stallion -- whose 36DD-30-50 measurements have made her an Internet superstar ... and recently scored her a major part in Major Lazer's "Bubble Butt" video.

We spoke with Elke who says she first met Brent through social media ... but the cyber-flirting escalated to the point where she decided to attend the USC-ND game in L.A. last month to meet Brent in person.

Elke says the two hit it off ... "He's a mad cool dude. Very respectful. Not an Idiot like the rest of them."

So how serious are they? Elke claims it's too early to tell ... but says "you never know" where things could end up.

Justin Brent -- the legend continues ...
