But after heading into London, Olivia has done just that while attending a special pop-up event!
The trio were pictured at the speakeasy style Walkers Crisp Sarnie Club, which is being held for a limited time in the capital to celebrate the launch of six new sandwich flavours of crisps.
While at the event, Alex got the chance to lie in a giant sandwich, before his girlfriend Olivia and their fellow Love Island co-star Cara jumped on top.
Oo-err! If it wasn't for the photographic evidence of exactly what went on, it could sound a bit dodgy!
Sharing the snap on Instagram, Olivia joked: "I mean, who wouldn't want @ab_bowen in a sandwich topped with an Olivia and a @miss_delahoyde yum yum."
We bet Cara's boyfriend and fellow Love Island winner Nathan Massey was so jealous he wasn't there to join in!
