Simon managed to get her shirt on and was getting some assistance with her pants.

"Almost there…" Brittany pulled tight and was met by a scream from Simon.

"Ow! A little tight around the family jewels, Britt. Now let's get this over with."

Simon ran toward the kitchen and found his brother facing away from him. With his best 'Brittany voice', Simon approached Alvin.

"Hey, how about giving me a shot at those lips of yours?"

Before he could respond, Simon spun him around and planted a kiss onto his lips. Simon then ran back into the bedroom where Brittany was waiting. He quickly removed her clothes and replaced them with his own.

"That was humiliating. Why did you have me do that?"

"Can you keep a secret, Simon?"

"Of course. What's going on?"

"I can't make it to the concert tonight. I have a photo shoot. If I go, I could secure some future deals for the girls and me."

"Brittany! They are going to be disappointed."

"I know. That's why I had you do that. You and Alvin are kinda close in size. I just wanted to see if my outfit would fit him."

"Wait a minute… Are you saying that you want Alvin to take your place tonight?"

"It's either that, or we cancel the show. I'm going to write a note and have Alvin deliver it. Promise not to tell?"

"All right. Good luck tonight, Britt."

Simon left the room and rejoined his brothers. Still shocked over what had just happened, Alvin approached his brother cautiously.

"Si, is there something you wanna tell me? Brittany doesn't even kiss me like that. And why were you wearing her clothes?"

"I was dared to."

"Dared? I think she was having fun with you, Simon. She was probably laughing the entire time."

"I know. It's over with now, so let's just forget about it and move on."

"Not quite yet, Si. Come over here."

Simon walked over to Theodore and was given a hug. Theodore then reached around and slapped him on the butt, causing him to yelp.

"He he… Should I start calling you Brittany, Simon? Or how about little miss chipmunk?"

"Okay, that's enough…"

Ignoring his demand, Theodore and Alvin continued making fun of him.

"Simon's got a boyfriend! Simon's got a boyfriend!" chanted Alvin.

"I heard he was voted miss chipmunk usa!"

Now angry, Simon ran from the room and went back to Jeanette. He gave her a kiss, causing the other girls to take notice.

"Simon! What has gotten into you?"

"Trying to prove to the guys that you're the one for me."

"I really appreciate the love Simon, but our bus is here. We really need to get going. Which reminds me, where is Brittany?"

From the kitchen they could hear Alvin and Brittany talking, but did not understand their words.

"Come on, Britt. We're ready to go."

"Okay. I'll be right there."

She joined her sisters on the bus a few minutes later. As it pulled away, Alvin took a seat next to Brittany and grabbed her hand, giving it a light kiss.

"Good luck tonight, girls. How about we have some fun after the concert to celebrate?"

"I like the sound of that! It's a date, Alvin."

Eleanor motioned for Theodore to join her, which he eagerly did. She rested her head on his shoulder and stared out the window.

"We're almost there, ladies. You ready for one last concert?"

"As always." Jeanette said as the bus came to a stop. Ready Eleanor?"

"Of course. Brittany?"

No response.

"Hello? Where did she go?"

"Relax. I'm sure she'll be around. She's probably already inside, girls."

"Thanks, Alvin. See you backstage."

As the girls left the bus, Alvin removed Brittany's outfit from under his seat along with the note attached to it. He then left the bus and started toward the dressing rooms. Jeanette opened the door expecting Brittany, but was shocked when she saw Alvin holding her outfit.

"Where's Brittany? The show starts in an hour!"

"She had to go to a photo shoot a few buildings down the street. She said it was to secure future concerts and other deals for you three. Here, read the note."

Jeanette grabbed the note and started reading.

'Girls, I'm sorry I couldn't make it there tonight. I hope you two have a great concert without me. Alvin should make a decent replacement. Just make sure he raises the pitch of his voice a bit and you'll be fine. Love, Brittany.'

"Great! Just great! She ditches the last night to have her picture taken."

"What are we going to do?"

Alvin started to sneak out of the room, but was quickly noticed by Jeanette.

"Oh no you don't mister. You come back here. Eleanor, help me take his clothes off. Alvin, you can fit into her outfit, right?"

"Uhh…."

The duo quickly wrestled Alvin to the floor and in seconds had him naked. Jeanette was finishing up with the top half just as Eleanor was going to grab Brittany's spare shoes. Alvin groaned as the pants were tightened and the shirt tucked into position.

"Almost done. Jeanette, get the combs while I get the makeup."

Alvin started pouting to himself but was met with silence from the others. Jeanette started combing his hair with her right hand while putting it in place with hairspray. Eleanor grabbed Alvin's hands and started putting on pink nail polish.

"Brittany is SO lucky I love her…" Alvin said to himself.

"Almost there, Alvin. Just have to fluff up your tail a bit."

Jeanette ran the comb through his tail a few times before joining her sister. They turned Alvin around and led him toward the mirrors. He screeched at the sight.

"Wow. A perfect fit. Are you sure you're not part chipette, Alvin? You look just like Britt."

"Ha ha. Very funny. This is humiliating! I'm going to embarrass myself out there."

"No you won't."

"Yes I will, Ele. I'm not doing it!"

"Alvin, please do this. For us? For Britt?"

"Oh all right. Let's get this night over with…"

Jeanette led the way with Alvin in the middle and Eleanor bringing up the rear. They stared at the empty stage, then back to each other. Alvin then spotted his brothers fast approaching. While Theodore was busy laughing, Simon snuck up to him and gave Alvin a pat on the back.

"Go get 'em, bro. Remember your voice. Raise the pitch a little and you'll be fine."

"Thanks."

Alvin stared at the ground as he could hear the announcer start the introductions:

Ladies and gentlemen, they have sold millions of records, performed for hundreds of sold-out shows and tonight, they are back home for you. Please welcome The Chipettes!

"Well, here goes nothing…"
