The reality TV stars, who recently denied that their blossoming relationship is just a 'showmance', shared their holiday snaps with their hundreds of thousands of followers on Twitter.
Other pictures include the couple sunbathing next to each other on a boat, Arg riding a horse and Collins passed out on the sofa, accompanied with the tweet: "In bed after a great night, Eduardo's then BushWhackers lol. Only thing missing is my Diana Doors! X"
Arg and Gemma returned to the sunny part of southern Spain where ITV2's The Only Way Is Essex special was set last month.
