Real Housewives of Beverly Hills star Kim Richards may have been placed under a 5150 hold last week, but the show goes on!

On Saturday Kim's sister Kyle Richards and co-star Lisa Rinna lunched and shopped as reality TV camera rolled, and the ladies were in a great mood. Kyle wore booties and a flirty black number while Lisa just killed it in tight bandage dress. How on earth is she 52?! She has the body of a 25-year-old -- and she clearly knows how to dress herself!

Kyle smiled for the cameras, but we do have to wonder how she's holding up. Last week Kim was hospitalized for 72 hours on an involuntary psychiatric hold, and after that it was reported that she checked into rehab, but the following day a source told E! News that Kim was not in a program.

Kim has been struggling with alcoholism for quite some time, and earlier this month she was also arrested for shoplifting at Target in Van Nuys. The troubled star spent the night in jail before being released on $5,000 bail.
