He took to Twitter to hit back at those that had previously questioned the pair's romance. Alex tweeted: "People that doubted me and Olivia."
He then added a slew of crying with laughter emojis and one of a middle finger.

That's one way to shoot the doubters down, right?
That, and the fact, that Alex and Olivia couldn't seem more smitten with each other. In fact, Alex is currently preparing to move in with his co-star girlfriend in her hometown of Essex.
Yup, Alex recently revealed that he and Olivia are taking a BIG step when it comes to their relationship, and will be setting up home together. He is ditching Birmingham for Essex and is set to join Olivia in her pad next week.
Confirming the news on Twitter, Alex told fans he couldn't wait to start a "new chapter" with Olivia. She, meanwhile, gushed: "My man moving to Essex, couldn't be happier! @ab_bowen07"
Alex and Olivia got together while starring on Love Island's second series. Olivia had expressed her concerns over Alex's womanising rep, but he reassured her that he only has eyes for her.
Since then, their relationship has been going from strength to strength.
Reveal caught up with Olivia recently and she told us: "Things have been amazing between us - we've dropped the L-bomb which is crazy... It's all moving really quickly but it feels really natural."
She also slammed claims that her and Alex were putting on a 'showmance', and added: "No way, that's bulls**t. Maybe with other couples but for me and Alex it isn't a showmance," she told us defiantly. "If I wanted that I'd have gone for someone else. I love him and he's beautiful."
Olivia and Alex finished in second place on Love Island. They were beaten by series' winners Cara de la Hoyde and Nathan Massey.
