Just hours after James Kennedy’s arrest, Ally Lewber hosted an event.

Lewber stepped out solo on Wednesday, December 11, to host clothing brand Windsor’s New Year’s Eve bash at the Short Stories Hotel in Los Angeles. This followed her arrest on December 10th Vanderpump Rules Star boyfriend on suspicion of domestic violence at their shared home in Los Angeles.

The 28-year-old astrologer smiled in the photos as she posed for cameras and mingled with the star-studded event. She even got a short-lived tattoo from The Tattoo Shop and posted on social media throughout the night.

It is unclear whether Lewber was the victim of the domestic violence, but a spokesperson for the Burbank Police Department tells PEOPLE that she responded to a call about an argument between Kennedy and an unnamed woman around 11:30 p.m. on December 10 would have.

According to TMZ, which first reported the news and cited law enforcement sources, the caller witnessed Kennedy becoming violent toward the woman. Although authorities found no injuries when they arrived at the scene, Kennedy was taken into custody.

“The investigation determined this was a domestic incident that led to (Kennedy’s) arrest,” the rep told PEOPLE. “(Kennedy) was charged with domestic violence and later released on bail. The formal charges remain pending review by the Burbank City Attorney’s Office.”

The 32-year-old DJ and Lewber attended Kathy Hilton’s annual Christmas party together earlier in the evening. A source told PEOPLE that the two spent much of the event apart and didn’t show much affection for one another.

Another insider told PEOPLE, “James behaved extremely aggressively throughout the night.”

“He was acting so erratically, running back and forth to the bar, checking on people as he went,” the insider claimed. “He seemed drunk. Spent most of the evening alone, but when he spoke to people he seemed irritable and rude.”

Kennedy and Lewber did not respond to PEOPLE’s request for comment.

Kennedy was also active on social media following the alleged incident, sharing an announcement on his Instagram about an upcoming DJ gig.

“I can’t wait to be back at my favorite place in DALLAS!! 🔥🤠 @komododallas,” he captioned the photo.
