The reality star was not only looking oh-so-fab at this year's National Television Awards, but she was also feeling great after embarking on a new diet and fitness regime.
Speaking to the Mirror, she said: "I've lost a stone... It's not easy but I feel great."
Well, it's certainly paying off, as Gemma showcased her hard efforts by rocking the NTAs red carpet in a flirty LBD. And we absolutely loved the tuxedo-style dress!
Addressing her recent weight loss at the event, the blonde beauty admitted her time on I'm A Celebrity kickstarted her lifestyle change.
Although Gemma had hoped she would shed the pounds while in the jungle, she only managed to last three days in camp before quitting the show.
Now, the 33-year-old has decided to take matters into her own hands instead.
She said: "It's the first time I've really done it properly.... I just said 'this is it, I need to do this', so now I am doing it."
In the past, Gemma admitted she relied on fad dieting methods, but nothing seemed to work for her.
"There's no diet I haven't done," she claimed. "Now I'm eating sensibly, having proper healthy meals and exercising regularly."
Meanwhile, Gemma was back in the company of her I'm A Celeb campers at the star-studded awards bash and she was even spotted stealing a cheeky kiss from Jake Quickenden.
Although Gemma never got to meet Jake when he was in the jungle, the X Factor star has certainly made an impression on the Essex girl.
Earlier today, we revealed how Gemma wants to "have Jake's babies" this year.
