Blac Chyna delivered a keynote address on ‘Building Your Brand’ at the Los Angeles Ultimate Women’s Expo on Saturday.

The 33-year-old model was all smiles when she greeted her fans and took the stage at the Los Angeles Convention Center.

Chyna’s public appearance comes after news broke that she’s under a police probe in connection with an alleged incident at a Sacramento H๏τel last month.

The Washington D.C. native, whose real name is Angela Renée White, donned an all-white ensemble consisting of legging, a high-necked top with a built-in corset and a crocodile jacket.

Chyna’s cropped jacket featured long pieces of fringe that hung from the shoulders and the hem. She sported white sneakers and wore her long dyed-orange locks down in loose waves.

The influencer who is mother to five-year-old daughter Dream with Rob Kardashian, 34, and son King, nine, with rapper Tyga, 32, beamed as she held the microphone and chatted with KTLA anchor Lynette Romero.

She is under police investigation for an alleged incident on November 27, Page Six reported, in which a woman said she was held ‘hostage’ in a Sacramento H๏τel room for 20 minutes.

The reality star was said to have hosted an after-party at the Sheraton Grand after a Black Friday event, where things escalated verbally to the point where one woman was barred from leaving Chyna’s H๏τel suite. A portion of the alleged incident – which went down around 3 a.m. – was captured on video by The Sun as shared by a partygoer who recorded his hysterical friend sobbing after she fled the H๏τel room.

Chyna’s attorney said that ‘the story is false.’

Partygoer Ron Knighton provided The Sun with two minutes worth of video and recounted the events of the evening of November 26, into the early morning hours on November 27.

Following a Black Friday party at the 3M Event Center in Penryn, California — where Chyna was a special guest — she hosted an after-party in her H๏τel suite.

‘Everyone was enjoying themselves; the drinks were flowing and the energy in the suite was real good,’ Knighton shared.

‘Suddenly out of nowhere Chyna just yelled at my friend to “shut the f**k up or she’d beat both our a**es”.’

‘The vibe immediately changed so at that point we thought it was best to leave – but when I went to walk out she shut the door behind me and kept my friend in the room,’ he continued to share.

Knighton maintained: Chyna ‘wouldn’t let her leave even though my friend was crying and shouting – she was being a total bully.’

In the video, Chyna’s sobbing friend was seen escaping the H๏τel room once Chyna opened the door to let a few people in — at which point she tried to grab the girl back inside by her hair.

After fleeing, the Rob & Chyna star could be heard telling them to come back in. ‘We aren’t staying anywhere. We are leaving! You crazy?,’ Knighton says.

The pair then try and make their way to the elevators at which point he tells his friend he ‘wanted to kick the door in,’ as she sobs.

As the elevator door opens and they go to get in, Chyna is seen with a group in the hall trying to get to Knighton and his friend but is restrained by a larger gentleman.

The friends successfully make it into the elevator at which point they have a conversation where the woman cries ‘she’s so mean’ at which point a friend says: ‘It’s not your fault — she’s high on cocaine and crazy.’

Despite the claim that there were drugs present, the video doesn’t indicate such or capture what actually went down inside the H๏τel room.

The Sacramento Police Department told Page Six: ‘A dispute between two parties occurred, and the incident was resolved at the scene by the individuals involved. No injuries were reported.

‘The department is actively investigating the circumstances surrounding the incident and the investigation remains active.’

Chyna’s attorney, Lynne Ciani, denied any wrongdoing on Chyna’s part to the publication and called it a ‘false accusation.’

‘This story is false. This latest false accusation of criminal conduct is just the most recent in a long line of false accusations against Blac Chyna,’ Ciani’s statement began.

‘…We are hopeful that one day people will stop falsely accusing Blac Chyna of criminal conduct. Until that day, we will continue to disprove these false allegations to law enforcement and in the courtroom, if necessary.’
