The reality TV star, 22, channeled her inner Anastasia Steele when she chose to wear a very racy top on Saturday night (14 March).
We're not sure it actually classes as a top, though... More like a saucy bra!
The sexy señorita, who dropped from a size 16 to an eight over three years, showed off her slim frame in the S&M-style corset, which she told fans was from Lasula Boutique.
She tweeted: "Feelin 50 shades in @LasulaBoutique S & M number."
We reckon boyfriend Kyle Christie would've had to pick his jaw up off the floor!
Over the weekend, Holly also showed her softer side when she shared a bare-faced selfie with her fans.
With her hair tied up in a messy ponytail and not a scrap of make-up on, Holly joked: "Woke up like dis #freshasapineapple."
Fans liked her more natural look, with one saying: "So pretty just like that with messy hair and no make up."
And we have to agree!
See Holly and the Geordie Shore gang when the 10th series kicks off on MTV, 10pm, Tuesday 7 April.
