"James is trying to win everything back including [girlfriend] Ally [Lewber]," a source exclusively tells Us Weekly. "If he doesn't stay sober, he knows he has a lot to lose."

According to the insider, Lewber, 28, is keeping her distance for now as Kennedy prioritizes his sobriety. The source adds that Kennedy is "staying sober and getting treatment. He's taking it [very] seriously."

"Ally is staying away until he gets help and she is leaning on friends and family." the insider says. "People are rallying around her. She has a lot of support."

Kennedy's reps did not respond to Us' request for comment.

Kennedy, 32, was arrested on Tuesday, December 10, after law enforcement received a call "regarding an argument between a man and a woman" at Kennedy and Lewber's home. Police deemed it to be a "domestic incident" and Kennedy was subsequently taken into custody.

After news of his arrest broke, Kennedy's attorneys spoke out in a statement to Us.

"We are in the process of conducting our own investigation into the allegations levied by the Burbank Police Department against James," the December 13 statement read. "We understand that there were no injuries and we are hoping that, after careful review, the city's attorneys will decide not to file formal charges."

Kennedy and Lewber started dating in January 2022. Three months before they met, Kennedy and his former Pump Rules costar Rachel Leviss called off their engagement. In March 2022, the DJ and Lewber made their relationship Instagram official, showing off pics from the couple's vacation to Tulum, Mexico.

Lewber, for her part, has remained out of the public eye since Kennedy's arrest made headlines, but she took to social media to let everyone know how she was faring.

"Thank you to everyone who has reached out with love and support and for checking in on me," Lewber wrote via her Instagram Story on Saturday, December 14. "I'm OK and taking the time I need right now. I deeply appreciate all the kindness and respect for my privacy during this time."

A second source previously told Us that Lewber's parents came "into town" and the group have been staying in "an Airbnb."

One week after his arrest, Kennedy broke his silence, sharing how he was prioritizing his commitment to being sober.

"I am committed to making meaningful changes in my life," the Bravo star shared via Instagram Stories on Tuesday, December 17. "I am taking time to focus on my sobriety, personal growth, and being present for my loved ones. Navigating challenging moments is not easy but I am determined to learn, grow and move forward with the incredible support system around me."
