The Band Perry, much like the rest of the world, are thrilled with the news that Carrie Underwood and Mike Fisher are expecting! They're even offering up their services -- their babysitting services -- to the couple.

Although Kimberly Perry may not quite be ready for a baby of her own, she is ready to help Underwood take care of her upcoming bundle of joy. The sibling trio look at Underwood as not just a fellow artist, but a friend, and they are very excited for the 'Blown Away' singer and her hubby.

"We told them we would babysit if they ever need us to, so we are here, give us a call," singer Kimberly told E! News during the 'Fashion Rocks' event.

The trio even have a little time to prepare for the job and to read some babysitting books, since they've known about Underwood's pregnancy a little longer than the rest of us.

"Well, you know Carrie is a dear friend of ours and she was at my wedding, she and Mike," Kimberly says. "We actually heard the news a little bit early before the rest of the world did and we are just so thrilled for them!"

Kimberly even gushes that her dear friend will also be a great mom, and Fisher a great dad!

"They are just such great human beings and they are going to be great parents."

Underwood announced her pregnancy in a very clever Labor Day social media post. It is the first child for her and Fisher and less than a week after the announcement, she showed off her growing baby bump at the Ravinia Festival.
