The Chipmunks and Chipettes are no 20 years old and it's been a couple of month's now since Alvin and Brittney along with their siblings have been married. And now they have a little surprise.

"Alvin"

"Yeah, Britt." Alvin was looking at her and Brittney was looking down at her stomach and started rubbing it.

"No way are you serious!" Alvin said with a huge grin across his face.

"Yeah that's right you're a father" Brittney said with a smile and a little giggle.

"Well come we got to tell your sisters and my brothers the big news". They got in the car and headed over Simon's and Jeannette's house. They got out of the car and rang the door bell. Simon answered the door and looked surprised.

"Alvin Brittney? Well this is a surprise me and Jeannette were just heading over to your house"

"Well that can wait we got big news" said Brittney. Simon invited them in.

"Simon who's at the door?" asked Jeannette, that's when she saw Alvin and Brittney come in.

"Brittney!"

"Jeannette!"

"We have some exciting news" exclaimed Brittney.

"So do we" exclaimed Jeannette.

"On the count of three, one, two, three!"

"Your becoming an Aunt, huh, are you serious!" they both said in unison they also squealed.

Alvin and Simon were hearing the girl's conversation while they were drinking water but when the girls finish talking the boys took a spit a take…

"You're a dad. Yeah. Congratulations" said Alvin and Simon in unison.

They talked for a couple of minutes and decided to tell Theodore, Eleanor, Dave, and Miss Miller the big news.
