The 50-year-old Dance Moms star was spotted at Craig's restaurant in Los Angeles on Monday night, sporting an all-black outfit and sandals. Miller wore a big grin as she exited the celeb hot spot, looking upbeat for the cameras.
Miller is expected to surrender to the FCI Victorville facility in Victorville, California, on Wednesday at 2 p.m. to start her 366-day prison sentence. In May, she was found guilty of bankruptcy fraud in Pittsburgh, Pennsylvania.
ET spoke with the reality star at the MARVEL UNIVERSE LIVE! AGE OF HEROES red carpet premiere on Saturday in L.A., where she opened up about how she's spending her last few days before serving jail time.
"Right now I just kind of want to enjoy some laughter and some fun," Miller said, adding that she was spending time with close friends.
She also said her jail stint will give her some much-needed "me time."
"I'll just have me to concentrate on and that’s different," she explained. "I’ve always put everybody else’s child first before my own health, before my own outfit, before my own time frame. Everybody else was dressed and out the door and looking perfect and I was running around trying to find a clean towel to take a shower with, so I think this will be a little 'me' time."
