The Essex favourite looked fresh-faced and younger than her years in the photo, taken alongside her co-star and best friend Bobby Cole Norris.
She added the caption: "Me and my Bob #nomakeupselfie. Cardiff here we come x."
It's not often we see a TOWIE girl without her fake lashes, perfectly contoured bronzer and glossy lips – but we reckon ditching the slap makes Gem look younger than ever!
Gemma's fans were quick to compliment her in droves with comments including, "Wow, looking really good with no make-up Gemma! So much more beautiful!" Another said: "Oh my gosh Gem, you look so much younger! Be more natural, you beauty."
Later that night, Gemma flaunted a show-stopping make-up style while out in Wales with Bobby, sharing another picture of them glammed up and looking fabulous.
On last week's episode of TOWIE, viewers saw Gemma set up on a blind date by friend Ferne McCann - only for Gemma to then realise she'd actually snogged the guy at Sugar Hut a while ago.
It could have been rather embarrassing but our Gem managed to laugh it off and enjoy a fun date with Gino - even if she did think the 23-year-old was probably a bit too young for her.
