The couple headed to the Spanish city for their first holiday together and judging by the snaps, Lewis and Marnie couldn't be more smitten.
Neither Lewis or Marnie tweeted any updates during their break, but they did both treat their followers to a few photos on Instagram. Marnie posted a cute snap of the pair cuddled up together while out and about in Barcelona, tagging Lewis alongside her post and adding a love heart emoji.
Lewis, meanwhile, shared a photo of himself and his girlfriend at a football stadium and added the caption: "My hearts in Barcelona @marniegshore."
He also added another of Marnie posing by a water fountain while they duo were out sightseeing and gushed: "She's the only sight I need @marniegshore."
Responding to his post, one fan commented: "That's so cute I really hope u last (sic)." While another said: "Aw man hope you's are truly happy xxxx (sic)."
Lewis and Marnie got together while starring together on Celebrity Big Brother. After just ten days together in the house, Lewis confessed that he was in love with Marnie and from then, their romance seemed to go from strength to strength.
So much so, that on his exit from the house, Lewis openly shared his hopes to marry Marnie one day in the future. He spoke of a five year plan during an appearance on Loose Women and told the panel: "I think, if I am with Marnie in five years time, I'd be surprised if she doesn't have a ring on her finger."
Marnie, meanwhile, made it to the CBB final and finished in fourth. She told host Emma Wills that she thinks Lewis is "definitely The One" on her exit and has since hit back at claims the couple are putting on a showmance.
Marnie told Daily Star: "We have been offered all kinds of magazine and TV interviews, but we are keeping it private for the time being because we don't want to put a strain on our relationship. There was so much talk of us being a 'showmance', but the funny thing if neither of us are the type of people to court the media for money or fame."
