This one is kinda filled with Christmas (even though it's summer) but it just fidded with the story!! Anyway, here is the story, enjoy!!
-With Selena in her dressing room-
SG: *getting ready*
JB: *walks in* Hey *smiles*
SG:*turns around* Hey *smiles* What's up?
JB: I have someone who wants to meet you *steps aside*
JZ(Jazmyn Bieber): *standing behind Justin, nervously holding his legs*
SG: Hey *smiles and walks to Jazmyn; kneels down*What's your name?
JZ: *doesn't say anything*
SG: Come here *holds her arms open for Jazmyn*
JZ: *walks to Selena*
SG: *picks Jazmyn up* Hey, I'm Selena, what's your name?
SG: That's a beautiful name! *smiles* And you're Justin's little sis?
SG: Well, you're just as sweet as he always says
SG: You're gonna watch the show with me?
SG: First you have to watch with Justin, because I have to perform, are you gonna watch?
JZ: Yes! *smiles*
SG: Okay, let's go! *walks out of her dressing room while holding Jazmyn*
JB: *following her* You're really good with kids *smiles*
SG: Thanks *smiles*
JB: Come here Jazzy, Selena is about to go onstage and I don't think you wanna go with her, do you?
JB: You do... oh
SG: *laughs and whispers something in his ear*
JB: *nods* Okay, I'll do that
SG: And we're doing 'All I want for Christmas is you' right, since it's almost Christmas
JB: Yeah, I know *smiles* Good luck!
SG: *goes onstage* Hello everyone, how are you doing tonight??
SG: Let's get this party started!!!
SG: Since it's almost Christmas, I decided to do a Christmas song tonight, are you up for it??
SG: *starts singing* ~I don't want a lot for Christmas, there is just one thing I need.
I don't care about the presents underneath the Christmas tree. I don't need to hang my stoking there upon the fireplace. Santa Claus won't make me happy with a toy on Christmas day. I just want you for my own, more than you could ever know, make my wise come true!!
JB: *walks on stage with Jazmyn; joins her* All I want for Christmas is you!!!
SG: You baby! *picks Jazmyn up*
JB: Oh, I won't ask for much this Christmas, I won't even wish for snow. I'm just gonna keep on waiting, underneath the mistletoe. I won't make a list and send it to the north pole for Saint Nick. I won't even stay awake to hear those magic reindeer click. Cause I just want you here tonight, holding on to me so tight, what more can I do? Baby
SG: *joins him* All I want for Christmas is you *points at Jazmyn*
JB: *points at Jazmyn*
-After the song-
JB: Thank you! Give it up for my sister Jazmyn and the lovely Selena Gomez!!!
Crowd: *cheers; claps; screams*
SG: *walks off with Jazmyn*
JB: Selena? Could you come back for a second?
SG: *walks back confused*
JB: And sit down here *point to a stool*
SG: *sits down; still confused*
What's Justin gonna do?? Let me know what you think!! Love you all!!!
