Hot Vegas

Dog the Bounty Hunter squared off with an old opponent in Las Vegas and when fists started flying cops had to get involved.

Dog was at Luxor in Vegas Wednesday for a bail bonds conference when he ran into an insurance broker named Ronnie Frank, who's had beef with Dog in the past.

A rep for Dog says Frank got in a threatening stance and said, "I'm gonna kill you, you long-haired mother f*****." Dog's security guard tried to break it up by putting a hand on Ronnie's chest.

We're told Ronnie slapped his hand away, and that's when Dog's guard punched Ronnie in the face. Hotel security called Vegas cops, who cited Dog's guy for battery.

On a positive note for Dog -- Beth was voted President of the Bail Bonds Association later that day.

Mariah Carey is not lazy, she just has fab shoes that KILL her feet.

Video surfaced this week of Mariah getting wheeled around Caesars Palace to her show at the Colosseum. People chalked it up to diva antics, but our sources say Mariah was a victim of what she calls "shoeicide" -- wearing shoes that are super fabulous, but murder on her feet.

We're told Mariah walks around in her shoes constantly, but on this occasion ... she simply couldn't do it anymore. So Mariah's staff concocted the rolling chair to help ease her foot pain.

Celine Dion lost it during her Vegas concert -- the first time she's performed since her husband's death.

Celine was performing "All By Myself" when she broke down.

Celine added a tribute to Rene Angelil to her show.

It's tough to watch, but the crowd helps her through it ... it ends on a high note.

Celine Dion will return to her Vegas stage Tuesday for the first time since her husband Rene Angelil died, and she plans to continue paying respect to him.

We're told Celine's completely changing her show at Caesars Colosseum -- it now begins with a 10 minute long tribute to Rene.

Celine has 12 shows before going on hiatus in mid-March, so the tribute will be part of the act at least through then.

As her manager, Rene played a huge role in catapulting Celine to stardom. She's already had an emotional send-off for him at Montreal's Notre-Dame Basilica and a Vegas ceremony to honor him. Tomorrow night's opener should be another tearjerker.

A former Bellagio Hotel employee from the Philippines claims she was humiliated by her boss, who told her people from her country were direct descendants from monkeys.

Vilma Miel claims in a new lawsuit she worked as a cage cashier for nearly 20 years, but it went south in 2014 when her supervisor began harassing her.

She claims the guy called her an "old woman" and said Filipinos "originated from monkeys."

Discrimination aside, she also claims she developed carpal tunnel syndrome during the 2015 Chinese New Year. She says she hopped on a flight to the Philippines to get treatment, and when she came back she was suspended and ultimately fired.

Britney Spears' ideal guy is a mix between Bill Gates and rapper The Game.

Spears was performing at her Vegas residency Sunday night, but went a little off script when it came time to pick out a random guy from the crowd.

Brit got real specific, saying she needs a "hot nerd" -- innocent enough -- but it sounds a lot like she wants one who's packing in the right places.

MMA star Tito Ortiz was cited for misdemeanor battery early this morning after allegedly getting physical with a woman inside of a Vegas nightclub ... TMZ Sports has learned.

Here's what we know ...

Cops were called to Drai's Nightclub inside The Cromwell hotel around 1 AM -- where a woman claimed Ortiz got physical with her and tried to rip her phone away.

The woman tells TMZ Sports she had been taking pics inside the club earlier in the evening -- and she believes Tito must have thought she was trying to snap shots of him.

The woman claims Tito tried to "whip her around" -- and the incident was so frightening, she was "scared for [her] life."

When cops arrived to the scene, Tito was NOT arrested -- however, he was cited for misdemeanor battery.

We're told the woman is lawyering up -- and is considering her legal options.

The woman who claimed Chris Brown and his crew hit her and tossed her out of a Las Vegas party ... has now filed a lawsuit against him.

Liziane Gutierrez filed docs in Clark County, NV ... laying out the details of the story TMZ broke: She says she went to Chris' room at the Palms Hotel and Casino, and then someone -- Chris or someone in his crew -- hit her in the "face and/or arm and/or hands."

In the suit, she also says someone in the room took her cell phone.

Gutierrez is suing for battery, theft and also defamation -- over that video Chris posted calling her "too ugly" to be in his party.

As we've reported ... Vegas police cleared Chris of any criminal wrongdoing for lack of evidence.

NFL legend Jim Plunkett knows what SHOULDN'T happen in Vegas ... the Raiders playing there ... saying the silver & black moving to Sin City is a no-no.

Plunkett is a GOD in Raiders lore ... having won two Super Bowls with the team back in the day. So when we got him out in San Fran we needed to know his thoughts on rumors Vegas could be the team's new home.

Long story short ... he ain't with it.

Mariah Carey may have to get a restraining order against her billionaire fiance ... to keep him in his seat during her concert.

James Packer joyously and (arguably) adorably celebrated Mariah's return to her Vegas venue Tuesday night, busting a move that can only be called ... unique.

He's been her number one fan from the day they met ... blasting her music from the speakers on his gigantic yacht, and following her from concert to concert.

James is pretty much the only one rocking out as Mariah owned the audience, but hey ... who's gonna tell a multi-billionaire to chill?

Celine Dion tearfully recalled moments in her life with late husband Rene Angelil at his Vegas memorial.

Celine told the crowd in the Colosseum at Caesars Palace that she can "still feel his strength and his warmth."

She talked about how Rene kept her grounded, and how he hated no one.

Very emotional.

The owner of the Oakland Raiders tells TMZ Sports ... he does in fact own the domain LasVegasRaiders.com -- and has for years -- "just in case" the Silver and Black move to Sin City.

We spoke with Mark Davis who confirmed he personally bought the domain back in the '90s "in case the team ever wound up in Vegas."

"I think it's only $8 per year ... so, it's worth it in case we end up there."

When asked why he liked Vegas as a possible destination, Davis said -- "It's close to where we are now. It would be a close trip for our fans and there are a lot of sports fans who visit Vegas."

One other interesting thing ... Davis told us he believes the Raiders are the only NFL team that could "exist" out in Vegas.

So far, it seems Vegas could still be in the cards for the team -- especially with Las Vegas Sands honcho Sheldon Adelson gunning to build a $1 billion stadium on the UNLV campus.

Michael Phelps -- male stripper??

The folks at Chippendales hope so ... 'cause they were so impressed with the Olympian's Speedo stunt at the ASU basketball game last week, they want him to shake it onstage!

Celine Dion is about to take center stage for the first time since husband Rene Angelil died, but not to sing.

We're told Celine's back in Vegas where she'll honor her late husband Wednesday with a celebration of life service. The venue is the Caesars Palace Colosseum ... the site of her Vegas residency.

Celine will speak at the event ... but we're told there's no plan for her to sing.

Rene was laid to rest in Montreal at an elaborate funeral in the Notre-Dame Basilica. A day later, Celine buried her brother ... so it's been a rough start to 2016.

As we previously reported ... she's canceled her Vegas shows until February 23.

Chris Brown is in the clear ... he won't face criminal charges for allegedly punching a woman at a Vegas after-party.

We broke the story, Liziane Gutierrez filed a police report claiming Chris went off on her earlier this month at a Vegas hotel, punching her in the face.

But cops weren't convinced, not by a long shot. They shelved the case because her claim wasn't supported by enough evidence. Chris said from the get-go he never touched her and she's just pissed because his boys wouldn't let her into the after-party.

There was another sticking point. Liziane went off on Jason Derulo in August after she didn't make the cut at his after-party. She later claimed he tried to get the women who did attend do some nasty stuff ... again, all unsupported claims.

We've reached out to Gutierrez for comment ... so far, no word back.

Jennifer Lopez's booty just can't be stopped ... because it escaped during her show in Vegas.

J. Lo had just finished the last song at her Planet Hollywood show over the weekend and when she took her final bow it was just too much to bare.

Hell of an encore.
