Holly slipped into a strappy black monokini and was clearly pleased with the outcome, deciding that the time was ripe for a quick selfie.
Standing in front of her mirror, she took two gorgeous snaps of her sexy swimwear on Saturday (6 September). Holly added: "Ibiza in 1 week!!!!!"
One thing's for sure, Holly is in great shape as she showed off her toned tum in the swimwear number from her own collection with The Fashion Bible.
Leaving little to the imagination, the 21-year-old's monokini is bound to get her noticed when she jets over to the party island!
The star has been on a bit of a weight loss mission recently, having already slimmed down from a size 16 to a size 10 since she first hit our screens in 2011.
Holly told us: "It's scary when people tweet me old photos of myself from series 1 of Geordie Shore. I always have to double take to check that it is me!"
And just last week she was thrilled to be able to pull on a pair of skinny jeans which she thought she wouldn't fit into again.
Sharing a picture on her Twitter page, Holly said: "Totally gave up on these jeans a few month ago, so glad I took the before photo to see my progress! Very happy."
It wasn't long before her fans started to congratulate her on the weight loss and, ever the pro, Holly seized the opportunity to plug her new autobiography 'Not Quite A Geordie'.
On Sunday she said: "Thanks for all the weight loss comments I talk about my weight & losing it a LOT in my book."
A trip to Ibiza and a banging bod aren't the only things Holly has to be excited about right now. The star has been getting cosy with Geordie Shore newbie Kyle Christie and they recently attended an event together.
