The sales exec joined islander Tina Stinnes at Café de Paris on Saturday night (23 July) for a girls' night out.
And didn't she look incredible?!
Olivia showed off her fabulous figure in a flirty pink playsuit, slashed to the waist and cinched in with a skinny black belt.
Love the look? You can pick up this EXACT romper from FreeGirl.co.uk for £32.99. (FYIL It's called the Fall For Me Blush playsuit. How gorgeous a name is that?!)
Olivia was without Love Island co-star and boyfriend Alex Bowen on Saturday night, as he was doing a personal appearance in Chalfont St Peter. It was actually his birthday on 23 July, so before they parted ways for the night, Olivia had treated Alex to a special day out.
She told him via Twitter: "Happy Birthday to my Prince @ab_bowen07, hope you enjoyed all your birthday surprises - I had the best day with you."
He replied: "Thank you for everything."
They fell for each other in the Love Island villa and finished in second place, just behind Cara de la Hoyde and Nathan Massey who scooped the £50,000 prize.
After leaving Majorca, the couple did their first photoshoot and interview together with Reveal magazine, where Alex told us: "We're taking every day as it comes. But we're going to put 100 per cent effort in, so that's all that matters at the moment."
Olivia added: "I've got his best interests at heart and he's got mine, so we both want to do well, with each other."
