The 38-year-old reality star was spotted out and about in Atlanta this week while Christmas shopping and was happy to show off her slim figure. Dressed in athletic wear leggings and a long-sleeved gray shirt, she was all smiles while proving she's kept her weight loss promise.

"I can promise you I'm never going back to that size. I'm happy where I'm at," Shannon told PEOPLE back in April after she underwent weight loss surgery and drastically changed her diet and exercise routine, going from 460 pounds to a size 4.

At the very beginning of her weight loss journey, she wanted to drop the pounds to make her ex Mike "Sugar Bear" Thompson jealous at his then-upcoming wedding to his new love. However, over time it became much more than that.

"My goal when I first started this weight loss journey was to make Sugar Bear kind of jealous," she said. "But it's no longer about revenge. Doing all the surgeries really took a toll on me -- not just physically, but emotionally. I feel like [I'm] becoming the person on the outside that I always felt like [I was] on the inside."

When she made her big debut after shedding the weight, her daughter and “Toddlers & Tiaras” star Alana “Honey Boo Boo” Thompson, said, “She looks great. I’m really proud of her.”

While Shannon continues to drop jaws whenever she updates fans on how she’s been keeping up her weight loss, she barely turns heads back at home.

“It’s kind of crazy. A lot of people don’t recognize who I am until I talk,” she said. “It’s kind of like I’m in my own disguise. Normally when I walk through the streets, everybody notices me, and now it’s like nobody [does].”

However, she may not slip under the radar for much longer, because she’s headed back to your television screens in January for “Mama June: From Not to Hot” Season 2:
