The former TOWIE star took to Instagram to show off her slimline shape in a pair of black skinny jeans from her own range.
Wearing just the jeans and a black vest top, there was certainly nowhere to hide.
But Gemma looked sensational as she gave her followers a twirl and showed off her slim waist and pert "derriere".
She said the jeans were "designed to hold you in and make you look a million dollars".
Gemma said she'd had "loads of requests" about the denim she wears.
The reality TV star explained they were a "hold-you-in stretch fabric" and "very slimming".
"You look stunning," said one of Gemma's followers.
"You look amazing," said another.
I’ve been concentrating solely on my health recently and feel so much better because I have had TIME!!!!! Yes TIME !!! to focus on it.
Another added: "You always look great, girl!"
"Love these," another commented. "You look amazing!"
"Looking insane Gem," another said.
