The has not been a good year for former “Real Housewives” star Kim Richards. She was arrested Sunday for allegedly shoplifting at Target -- her second arrest this year. She was earlier arrested in April for public intoxication.

The star was reportedly arrested Sunday for allegedly stealing $600 worth of goods from Target. She was released on bail on Monday. It's still unclear whether Richards was under the influence when she was caught stealing.

A source close to Richards told People that the star’s behavior has been unpredictable of late and has become increasingly bizarre. She is also not on speaking terms with her sister, Kyle Richards. "Her family is so concerned. And they're fed up. She's cut herself off from friends and family who care about her," the insider revealed.

The insider added that the 50-year-old star has been “bouncing around” from her sister Kathy Hilton’s home to other friends, looking for stable living arrangements. The source said that Richards moved out of her house and placed her belongings in storage prior to her arrest. The source said, “She didn't have a chance to find a new place."

In terms of finances, Richards is said to have “mismanaged her money,” according to the source, adding that the mother of four is “wrecking her life” and “won't accept any responsibility for it."

E!News sources are also baffled by the former “Real Housewives” star’s not-so-decent activities. A source said, "Stealing is just so out of character for her under normal circumstances," while another said that Richards has been relying on the transportation service Uber and has not been living in her car.

In an exclusive interview with "Entertainment Tonight" in July, Richards attributed her relapse in April to family stress. She revealed that her son was unwell and her ex-husband, Monty Brinson, was very sick. The star also mentioned that she had to give away her dog and that she wasn’t speaking with her sister, Kyle. Richards added, "I love sobriety. I've always loved sobriety and relapsing was very hard for me. It was not easy. I have to say, don't take this wrong, but I really wanted to go to treatment because I needed a break from what I was going through at home." Richards checked into rehab in May and left in June.
