The MTV star was snapped heading to a nightclub with fellow reality starlets Jem Lucy and Charlotte Dawson on Saturday, 30 April ... despite having a flight the next day.
Ouch. Brave girl!
"The fact I'm going wild tonight and have a flight to get tomorrow is kinda worrying," she admitted, before agreeing with one Twitter follower who suggested: "Just party all night and stay awake till you get on your flight."
Olivia found fame on the fourth series of Ex On The Beach, where she was an original castmember but joined by ex James Moore, which caused PLENTY of fireworks and drama.
Now, she's rumoured to be appearing in the fifth series of the MTV show as well... which may explain why she was on a night out with Jem Lucy and Charlotte Dawson, also rumoured to be among the EOTB 5 cast.
As always, MTV won't confirm the lineup until nearer the air date.
But the trio have been causing headlines already with allegations they all hooked up with fellow rumoured co-star Gaz Beadle, though they haven't confirmed or denied that speculation.
Sounds like the new series could be even more explosive than the last...
