The new year is off to a bumpy start for RnB badboy Chris Brown. The “Loyal” singer, 26, has been forced to deny hitting a Brazilian model at a Las Vegas hotel in the early hours of Saturday.

And police in the city are now investigating claims that Liziane Gutierrez was assaulted at the Palms Casino Resort and had her mobile phone taken off her.

The RnB star’s publicist has issued a statement calling the woman’s charges “unequivocally untrue”.

The star, above, is accused of punching Liziane in the right eye because she had sneaked her mobile phone into the private party he was holding in his suite at the Palms Hotel.

Chris’s representative, however, insists Liziane, who did not seek medical attention and called police a few hours after leaving the party, was escorted out of the after party for “being disruptive and out of control”.

While waiting for security to bring out her phone, she allegedly had a “total meltdown,” which was caught on the hotel’s security cameras, prompting the venue’s security staff to step in and assist in removing her from the resort. The spokesperson added: “Her claim she had her phone in her possession inside the after party and was able to take a photo causing an ­altercation with Chris Brown is a complete ­fabrication.”

According to US reports, Las Vegas police attended the hotel to speak with Chris but were not allowed in the room – though they later determined he was not there any more.

Chris, who assaulted his ex ­girlfriend Rihanna in 2009, posted a video to Instagram and then later removed it, arguing that he didn’t know the model and that she was “probably too ugly to get in” to his room. Ouch.

In a later post, Chris added: “Keeping my circle small in 2016! I’m done taking the care of grown ass men.

“And I’m going to be hella rich after all the lawsuits I file from these crazy individuals who keep lying on my name. Happy NEW YEAR! Time for some of us to grow the f*** up!”
