The co-stars, who have split up but remain friends, apparently filmed themselves romping while they were in Marbella last month.
Lucy’s ex Mario Falcone was seen confronting her in last night’s episode of the hit ITV2 show after hearing the news from his friend Chris Drake.
Clearly fuming, he told Lucy: “You want to talk about disrespectful? Disrespectful is doing a sex tape in Marbella.”
But Lucy, 21, raged: “Disrespectful to who? Even if I did that how is it disrespectful? How many times did you cheat on me 30, 40?"
