Mama June Shannon was all smiles while showing off her new size 4 figure on Tuesday.

The 37-year-old Here Comes Honey Boo Boo star, who recently dropped 300 lbs. in a drastic body transformation, stole the show at the premiere of WE tv’s Growing Up Hip Hop Atlanta — walking the red carpet in a red halter-top dress with plunging neckline.

She accessorized her look with black heels, a series of rings, and a simple bracelet.

It was a far cry from the last time Shannon walked the Growing Up Hip Hop premiere red carpet — in January 2015.

Viewers watched Shannon’s stunning transformation on WE tv’s Mama June: From Not to Hot as the reality star spent upwards of $75,000 to have gastric sleeve surgery, breast augmentation and 9 lbs. of skin removal surgery on her “turkey neck,” “bat wings” and stomach.

“It’s kind of crazy,” Shannon told PEOPLE Now in April. “A lot of people don’t recognize who I am until I talk… 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],” she added.

Shannon — who weighed in at 460 lbs. at her biggest — previously told PEOPLE she plans on keeping the weight off with better food decisions, exercise and portion control.

“I can promise you I’m never going back to that size,” she said. “I’m happy where I’m at.”

With her weight finally under control, Shannon hopes her daughters Lauryn “Pumpkin Shannon,” 17, and Alana “Honey Boo Boo Thompson,” 11, will embrace the same lifestyle changes, though it’s not something she’s forcing on them. (Shannon also has a 20-year-old daughter Jessica “Chubbs” Shannon and eldest, estranged daughter child Anna “Chickadee” Cardwell, 22.)

I do worry about their health, but I’m not going to say, ‘You got to eat salads all the time,’ ” Shannon explained. “I’ve seen Pumpkin and Alana lose and gain weight, but I don’t want them to end up like I did at 460 lbs. Who would want that?”
