( PEOPLE.com ) -- `` The Real Housewives of Beverly Hills '' star Kim Richards entered rehab last week to seek treatment for alcohol abuse and `` other problems , '' a source tells PEOPLE . `` Kim has been to rehab more than once before , '' says the source , `` but every time is a new time , and everyone just hopes this sticks and that she gets the help she needs . It 's serious . '' Richards has been `` erratic . Everyone was really worried about her , '' says the source , who adds that Richards is not living with Ken , the boyfriend who was introduced as her love interest this season . During a recent episode of the Bravo show , Richards says she 's planning to move in with Ken , and cameras show her packing up her belongings . `` He 's not in the picture . No one really knows what the deal was with them , but Kim does n't live with Ken , '' the source says . `` She 's basically homeless , staying with various friends . She does n't have a home base . It 's not unusual for people to not hear from her for long stretches of time . It 's been that way for years . '' `` Her family is relieved she 's getting help , '' adds the source . `` She has lots of issues . She needs help . '' Viewers have watched Richards ' increasingly bizarre behavior and slurring of her words this season , which had been attributed at least in part to her taking anti-anxiety and antidepressant medications , along with an anti-seizure medication which can be used to treat alcoholism . Richards is receiving well-wishes from some of her colleagues since seeking treatment . Castmate Taylor Armstrong threw her support to Richards this week , telling Andy Cohen Monday night on his Bravo talk show `` Watch What Happens Live : '' `` I adore Kim and I stand behind her . And if there 's anything I can do to support her [ I will ] ; but if she 's getting healthy what more could we ask . '' See the full article at PEOPLE.com . © 2011 People and Time Inc.
