Audrina Patridge filed for divorce from her husband Corey Bohan.

On Thursday, the "Hills" alum filed for divorce due to domestic violence and cited irreconcilable differences. The couple has been married for less than a year and shares 1-year-old daughter, Kirra Max.

"Physically, Audrina is okay. But she's devastated," a source told People. "This is the end of a long-term relationship and she never wanted this to happen. It's a disappointment on so many levels, to say the least. It's painful and it's really hard." The insider added that Patridge's source of support is her family.

"Audrina is leaning on her family. She is extremely close with her parents [Lynne and Mark], brother [Marky] and sister and they are all supporting her," the insider added. "They're a very tight family and protective of her. They just want what's best for Audrina and Kirra."

In the documents obtained by TMZ, Patridge is divorcing Bohan due to his being abusive. A number of incidents that the "Audrina" star considered "menacing and emotionally abusive" prompted her to end their marriage.

According to Patridge, in August they argued because she accused him of cheating. Bohan pushed her while she was carrying their daughter. He also punched himself and threatened her that he will strike himself in the head with a metal canister if she left.

On Sept. 6, Bohan called her names and harassed her when she arrived home. However, the last straw happened over the weekend when Bohan showed up and followed her on stage of a beauty event and demanded where their daughter was. "I was shaking at this point," she said. On Monday, Patridge filed for a temporary restraining order, which was granted.

Patridge and Bohan had been dating since 2008. They dramatically split in 2011, but by December of the same year, Patridge hinted about their reconciliation. In November 2015, they got engaged, welcomed their daughter in June 2016 and got married November last year in Hawaii.
