The Geordie Shore star, 22, is using a waist trainer to cinch in her abdomen after losing three stone over a couple of years.
And we think she looks jaw-droppingly good!
Wearing the waist trainer with a hot pink sports bra and black leggings, Holly poses for the photo in her bedroom.
Alongside the snap, she says: "Wearing my waist trainer from @waistedbykeke thank you so much it's come all the way over from the U.S! Can't wait to start seeing results. Use code "Holly10" to receive 10% off #waistedbykeke #spon."
Her use of a corset divided her fans, with some believing she looks too thin and others warning of the dangers of using them.
But other fans told Holly she looked "amazing" and "sexy". Another fan called her a "transformation inspiration".
On the same day (4 April), Holly also shared a selfie flaunting her figure in a bright blue dress.
The frock certainly showed off the reality TV star's famous curves with its plunging neckline and super-short skirt! W-O-W!
Holly wrote: "Love this cute little blue dress from @officialrarelondon."
Meanwhile, another celebrity chose to try waist training over the Easter weekend...
Former child star Lindsay Lohan also shared a selfie wearing one of the controversial corsets.
She wrote: "Love my waist trainer from @NoWaistClique #MajorSituation http://nowaistclique.com."
Kim Kardashian and sister Khloe also admit to using waist trainers.
