Although Harry left the show for a second time last year, his name was referenced on Wednesday night's series closer while Gemma and Bobby Cole Norris were trying to patch up their friendship.
Bobby had admitted he was angry at Gemma for not telling him Harry had been cheating on him when they were together, suggesting it had even happened in Gemma's hotel room bed.
Gemma replied: "It didn't happen in my bed. I was staying in a five star hotel and Harry and his boyfriend couldn't afford the lap of luxury I was staying in."
That comment didn't go down well with Harry, who tweeted: "Still talking about me… Yawn. I see you yesterday, so u have been fake to my face didn't we spend the exact same on that holiday? U should be ashamed."
Harry and Bobby were together last year but in June it emerged that Harry had slept with an ex a week after starting to date Bobby.
At the time, Harry said: "I know it's no excuse whatsoever but me and Bobby were only together a week. I've made the biggest mistake of my life."
