No this isn't Purplenutellaaaa, it's Austlly394. About a month ago, me and Alaina decided that when I ended school we would do a colab story. Well I finished school, so here I am. Each chapter we will be alternating starting with me. I hope you guys like my writing. This story was most of my idea with a few tweaks made by Alaina. She loved the idea immediately. So it's not like I forced her to like it or anything like that. And no hate on me. Me and Alaina have become really great friends over the past 4 months. So pretty please with Auslly on top, no hate. Here's chapter 1 of, "The Biggest Mistake" I don't own, "Austin & Ally"


3 Years Ago Ally's POV

Today I, Allyson Michelle Dawson, am getting married to Gav- I mean, Austin Monica Moon. My one true love. I love Gav- Austin so much. Today, August 24th, is going to be the best day of my life. Hey there's Trish.

"Hey, Trish." I greet.

"Ally, today is the biggest day of your life. You are getting married to Austin." Trish says.

"Yeah." I say.

"Come on."

She and Dez walk down the aisle and separate. My older sister, Andrea, and Austin's older brother, Adam, do the same. Dad and I lock arms and begin to walk.

"I love you, Dad." I say.

"I love you too." Dad replies.

Austin and I are face-to-face. Now I'm in the mood for pancakes…it's time for Austin and I to say our vows. I'm first. "Austin, from the day I met you I knew you were the one. My soul mate, my partner, my best friend. You were and will forever always be there for me. I…I...I can't do this. Austin I'm sorry." I run out of the church. I know that everyone is very confused. Trish stops me.

"Ally, what the heck just happened?" She asks.

"I can't do this." I say.

"Why?"

"Because I'm in love with Gavin!" I say.

"And I'm in love Ally!" Gavin announces. He came out of nowhere. I hop into Gavin's car and we drive off.


No One's POV

Yeah. Ally just left Austin for Gavin. Speaking of Austin, there he is.

"Where's Ally." Austin asks his friend, Trish.

Trish sighs. "She left…with Gavin."

"WHAT!?" Austin gaps. "I have to get her back! But it's too late. Come on, Trish. We need to tell everyone what happened."


Ally's POV

"Gavin, where are we going?" I ask.

"To your house. Get a week's worth of clothes." Gavin demands. Once we get to my house, I change into not a wedding dress and start packing at the speed of light.

"Now, where are we going?" I ask once again.

"Vegas." Gavin turns to face me. "Ally, will you marry me?"

"Yes!" I say.

Let me explain. For the past year, I've been cheating on Austin with Gavin. Yeah, yeah, yeah. I am aware that that's not very Ally-like. But I love Austin and Gavin. I just didn't want to break Austin's heart. But I'm pretty sure I just did. I didn't know who was the one but, now I know it's Gavin because I couldn't admit to loving Austin. Life was so hard and now it's not.


A Week Later No One's POV

"I now pronounce you Mr. and Mrs. Gavin Young."

"Ally, I have a surprise for you." Gavin tells Ally.

"What?" His now wife asks.

"Let's just say it's in San Diego."

"Oh. I'm happy. Happy for us." Ally smiles.

"Me too."


One Week Later San Diego No One's POV

Over the past week, Gavin surprised Ally with a house in San Diego. Gavin wanted Ally to live in a city that would remind her of Miami. He just wanted to make her happy. And it worked. Ally and Gavin were so happy together. And they continued to be happy until they got some news one sunny June day.


Late June Ally's POV

OMG! I have the best news to tell Gavin. It's something that we've been wanting for about 4 months. I'm super happy. Gavin is performing tonight but he should be home… "Gavin."

"Hey Ally. Tonight's show was the best. I met so many fans. I was the hit of the night." Gavin says.

"That's great. Listen, I have to tell you something." I begin.

"What is it, babe?"

"I'm pregnant." I say.

"Ally, that's great!"

"You're not mad?"

"Why the heck would I be? We're going to have a baby. And I could not be happier."

"I'm happy to have a child with my one true love. I love you." I say with a smile.

"I love you too." Gavin says. He kisses me. He is the best husband ever.


9 Months Later Ally's POV

Today is February 17th, also known as the day me and Gavin become parents. That's right I'm in labor and it's the best thing in the world! Note the sarcasm. This is the worst experience I've ever experienced. Life is sucking right now. At least we'll get to meet our baby. And find out whether it's a boy or girl. Yeah, we wanted to wait. However, we did decide on names. Avery Mackenzie, if it's a girl. And Gabriel Mason, if it's a boy. Adorable names right?

So over the past 19 months, I've been keeping in touch with my family and most of my friends. I know Austin still hates me and doesn't want to talk or even look at me. I just didn't love him the way I love Gavin. And our baby. Once I have our baby, I'm going to send everyone pictures. Gavin has become more famous and so have I. Ronnie let me keep my record deal and record at his studio in L.A.. Gavin actually signed with Starr Records in L.A.. Austin must have been mad.


Many Hours Later Ally's POV

I am holding my baby…girl in my arms. And I could not be happier. Avery Mackenzie Young was born on February 17th (Alaina's birthday) at 3:38 PM (the time I was born). She is the most beautiful baby I have ever seen. She has green eyes from Gavin and brown hair from me. She is absolutely stunning.

"Ally, she's beautiful, like you." Gavin gawks over Avery.

"Here. Hold your daughter. I want the cutest picture between the cutest people I know." I say.

"She's precious." Gavin says.

"So very precious." I smile. "Okay…got it."

"It's perfect. And so is Avery."

"Gavin, you're the best husband I could ever have." I say.

"And you're the best wife." Gavin kisses my head. And then Avery's head. She's sleeping. A sleeping angle.


Less Than 3 Years Later Ally's POV

"GAVIN, I HATE YOU SO MUCH! WHY WOULD YOU DO THAT?!" I yell at my husband.

"BECAUSE YOU MADE ME COME TO THIS!" Gavin yells back.

"I want to split up." I say, crossing my arms.

"Me too. I don't want to keep fighting. I just want to end this."

"So we agree. Tomorrow, we're getting a divorce." I say.

"Tomorrow." Gavin agrees.


After The Divorce Ally's POV

"Avery?" I try to get my daughter's attention.

"Yes, mommy?" She answers.

"Me and your dad aren't going to be together anymore."

"Why?" Avery asks.

"We don't want to keep fighting and the love isn't there anymore." I tell her.

"Okay."

"Later today me and you are going on a plane to my hometown. To live there." I say.

"Okay." She hugs me. I hug her back.


Many Hours Later Ally's POV

I decide to go to Sonic Boom. I know that Austin started to work there after I left. He's probably still mad at me... or he just misses me. Sonic Boom would remind him of me. So many of our firsts happened there. Song, realization of liking each other, and everything in between. To be honest, I miss Austin. He was my best friend. I wonder if he knows that Avery exists. Did Trish, Dez or my parents tell him? I did this behind Gavin's back but, he and Trish are Avery's god-parents. I'm some sneaky ex-wife.

I went home first to put everything away and get a car. My dad must be at a convention and my mom is living on the other side of Miami. I park my car and explain to Avery where we are and where we're going. She understands. She will be 3 in a little less than a month. It's about 6:30 PM, so Sonic Boom shouldn't be busy at all. That's a good thing. I don't want Austin to meet Avery with a busy store.

Great the only person I see at Sonic Boom is Austin at the counter. I open the door.

"Hi! Welcome to Son- ALLY!?" Austin exclaims. Avery sits on one of the benches by the drums.

"Yeah, it's me." I say. Austin hugs me. He must have missed me.

"I missed you. I missed you a lot, actually." He lets out.

"I missed you too." I say. And that's the truth.

"So, who's this little cutie?" Austin sits across from Avery.

I sigh. "This is my…daughter…Avery Mackenzie Young."

"You and Gavin have a kid?" Austin asks.

I nod. "Yeah. Listen, the reason why I'm here is because Gavin and I split up."

"Ally, I feel so bad. Did I have anything to do with it?" Austin hugs me. I missed his hugs.

"No. Gavin just turned into a real jerk." I say.

"I'm sorry."

"No, it's for the best. I don't want to be married to someone that treats me horribly, anyway." I say.

"Wanna come back to my house? I can close early." He suggests.

I smile. "That would be really nice."


Austin's POV

Ally is back. I want to forgive her. But she betrayed me. She left me for a guy that left her. I don't know. I just want Ally to be safe away from that jerk. I'll find Gavin one day. He doesn't want to find me. I needed Ally back in my life. And now that she is, I think I'm falling for her again.


So, that was the first chapter of, "The Biggest Mistake" How did you like it? Alaina will be back for the next chapter. Review it up.
