Travis Kelce has been pictured downing champagne and partying in a Las Vegas club while surrounded by scantily-clad women after leaving girlfriend Taylor Swift behind in Australia.

The NFL star landed in Sydney on Thursday morning to meet up with his popstar girlfriend after his Super Bowl victory and watch her perform one of her Eras Tour shows.

However, the couple’s reunion was short and sweet as Kelce boarded a flight just a couple of days later to return to the US for more celebrations in Las Vegas.

Kelce landed in Sin City at 8.30am on Saturday and wasted no time in returning to the dancefloor with teammate and best friend Patrick Mahomes, who was already in Vegas for a friend’s bachelor party.

But video and pictures obtained by DailyMail.com from inside the Lavo club in Las Vegas show Kelce with a giant magnum of champagne in hand.

While stood on the packed dance floor, Kelce can be seen downing the champagne as he celebrates with his friends.

Wearing a bright Hawaiian style shirt, Kelce was also said to be stood on top of his table as his group partied from 2pm to 5pm.

They then departed from the Venetian hotel in a party bus to continue their wild night elsewhere on the city’s iconic strip.

Travis is believed to be on board with most of the rules but some reportedly have him rolling his eyes.

One of Taylor’s new rules prohibits him from going to strip clubs, which he is ‘fine’ with, but another banning him from posing with female fans left him exasperated, a source told Life & Style.

‘He has no interest in playing a calculated media game if it’s going to make him think twice about every move he makes. That’s not his style,’ adds the source.

Kelce’s behavior has come under the microscope in recent weeks after Swifties identified a number of ‘red flags’ in their idol’s boyfriend.

He first shoved Chiefs coach Andy Reid and screamed in the 65-year-old’s face in an explosive rant during the Super Bowl.

Kelce and a number of other Chiefs players were then criticized for going ahead with a ‘scaled down’ party on the same night as the deadly parade shooting in Kansas City.

Kelce was seen in a Kansas City sports bar alongside several teammates and their WAGs – including Mahomes’ wife Brittany.

He was part of a small group that also included Chiefs punter Tommy Townsend, center Creed Humphrey, tight end Matt Bushman – and his wife Emily.

Sources told DailyMail.com that Mahomes booked the entire venue out for a select few members of the squad and their families.

Many of Andy Reid’s team stayed away following the attack which left one person dead and dozens injured in Kansas City.

Kelce had already come under fire on the same day after posing for a smiling selfie with a police officer while holding a beer in the wake of the deadly shooting.

He was also extremely drunk at the parade and could barely speak and stand up on stage without the assistance of his teammates.

Kelce and Swift both donated $100,000 to victims of the mass shooting.

He made the donation through a GoFundMe page, which showed a pair of $50,000 donations from his charity, the Eighty-Seven & Running Foundation – an organization that aims to help ‘underserved youth strive to become productive citizens.’

It is also Kelce’s third trip to Vegas in two weeks. He was also there earlier this week to play some golf and relax with friends before flying out to meet up with Swift in Australia.

The three-time Super Bowl winner watched his pop superstar girlfriend perform her Eras Tour Friday night and was fully embraced by his girlfriend’s loyal group of fans at Accor Stadium.

The lovebirds also enjoyed a sweet date at Sydney Zoo during their time in the city – a move that was criticized by animal rights organization PETA.

In one clip from Friday’s Eras Tour show, a grinning Kelce could be seen trading friendship bracelets with the Swifties. In another video, he waved at screaming fans as he walked by.

Swift decided to give two nods to her beau in the audience through her lyrics during the show.

During the second verse of her song ‘Long Live’ off her album ‘Speak Now’, Swift sang the line ‘We are the kings and the queens / You traded your baseball cap for a crown / When they gave us our trophies / And we held them up for our town.’

At the mention of trophies, Swift held her guitar up and seemed to point out in the direction of Kelce in the audience.

That drew cheers from the packed audience at the Accor Stadium in the Olympic Park suburb of Sydney.

Later in the show, Swift had an encore of her altered ‘Karma’ lyric, where she once again sang out ‘Karma is the guy on the Chiefs’ instead of ‘guy on the screen’.

After her stint in Sydney, Swift has six shows in Singapore before she has two months off. It’s currently unclear if Kelce will be making another trip to join her in Singapore.
