He gets jealous of your singing partner...
Harry: Harry had been on tour for a month so far and you forgot he was coming back for a visit today. You and your singing partner Beau Brooks (From the Janoskians) were round at you and Harrys apartment singing some of your favourite songs and goofing around since he was one of your closest mates as well. Harry suddenly walked in when you were making a youtube video and singing 'Stay' By Rihanna. You both burst out in laughter since this was the 8th time you needed to start again. Harrys jaw dropped for two reasons, there was someone in his house that he had never met before and was good looking and it was the first time Harry had ever heard you sing. "Hey babe," you say as you get up from your laughing fit and hug Harry, "This is Beau, my singing partner, he's from the Janoskians!" "You never told me you sing?" Harry said looking at you and pouting. You smile at the ground and blush. "I was scared you wouldn't like my singing..." "Wouldn't like your singing? what do you mean? and how do you know Beau likes your singing?" Harry says concerned. "Because I have known Beau since we were in diaper's, and we always sing together, always have, always will!" You look over at Beau who is chuckling and he says "Y/N, I need to go now, see you next practise and we will try and make the video, aha!" He hugs you and kisses you on the cheek. On his way out he turns to Harry "Nice meeting you bro!" and just before closing the door you say "Bye Beau, love ya" Harry immediately turns to you and stares. "What?" you say. He wraps his arms around your waist and puts his head on your shoulder, "I can be your singing partner:(" he says. "No, you cant Harry, your always on tour!" You say slightly mocking him.

Niall: You were starring the love interest in Justin Bieber's music video that you had told Niall about, he had came home from tour early to come and see you and Justin shooting the music video. It was on the beach in Ibiza and you were wearing the bikini that Niall loved on you. You had no time to go and see him before shooting but you managed to smile at him. Niall stood there looking around awkwardly while Justin and you lay on a beach towel together hugging before dragging you into the water for a long kiss with tongues. After you had done shooting Niall said nothing to you but couldn't keep his hands off you. "What are you doing?" You say to Niall. "Just showing everyone your my girl!"

"Yeah me and Y/N are going to bang after we've finished making this video!" Alfie said jokingly.
