The former sales exec-turned-reality star uploaded a picture to Instagram on Wednesday morning (3 August) showing her looking oh-so-gorgeous as she arrived at the airport for her flight to Spain.
Olivia chose an uber comfy outfit for her journey which, if you fancy getting yourselves, is available now at Lasula Boutique! The high waisted knotted leggings are £9, while the cropped top is also £9
She told fans: "Bye bye England, Hello Marbs! So looking forward to spending time with my girls."
The only downside? Saying goodbye to hunky Alex for a few days. "Gonna miss my baby so much @ab_bowen," she added.
Olivia and Alex finished in second place on this year's Love Island, just behind Cara de la Hoyde and Nathan Massey, who scooped the £50,000 prize money between them.
Since leaving the villa, things have been going from strength to strength for Olivia and Alex: they've exchanged 'I love yous' and are even moving in together in Essex!
Olivia recently told fans her life has "done a 360" since applying for Love Island, as she's found the love of her life and been given the chance to explore career opportunities she'd always dreamed about.
"I am an emotional little soul as you all know; I found the love of my life and I also found a whole new life of change and hard moments," she said. "Truly know the hard moments will blossom into the best memories and just need to keep going and keep being strong for myself, my friends, my family and my boyfriend. Thank you so much for your continued support and amazing comments. You're the ones keeping me sane."
