The injury on the star’s forehead appeared to resemble a nasty graze – and she wore her trademark blonde locks scraped into a pony tail.
Sophie, meanwhile, appeared a little bleary-eyed as she was snapped on the balcony of the pair's holiday apartment.
Also on the balcony were, what looked to be, the remnants of several glasses of champagne.
Casually-dressed Sophie sported a simple black t-shirt as she stepped out – also with sunglasses.
At one point she appeared a little downcast as she peered at the half-empty glasses in front of her.
Earlier in the week the radio presenter and Love Island host had taken to social media to share a selection of snaps of their vacation.
The two blonde beauties posed in what appeared to be nothing but blue and white striped towels.
The pals looked relaxed as they snacked on hot chips, oysters and corn chips and dip.
“Best way to end your holiday is with your best friends,” Jackie captioned the snaps.
Sophie Monk also took to Instagram to share the pics but also included a video of the two women mucking around with Sophie’s friend and former radio producer Oscar Gordon.
Sophie was filmed with chips up her nose with Jackie had two in her ears.
What’s more, it has been revealed that Jackie has been turning to her pal Sophie to help her cope with her split from Lee Henderson after 18 years together.
The couple separated back in October 2018 and Sophie has been a huge support for Jackie.
“Jackie has always been a shoulder to cry on for Sophie and now it's her turn to return the favour,” a source has previously revealed.
“The girls have been talking a lot, spending lots of time together and Sophie has been helping her deal with everything and get set up in her new place.”
