Carrie Underwood and her dogInstagram

Justin Timberlake isn't the only celeb to finally JUST join Instagram!

Country singer Carrie Underwood signed on to the photo sharing social site the day before Valentine's Day and hasn't stopped posting pics since!

Carrie's first Instagram was a selfie picture (check out Miley Cyrus' latest selfie!) with the caption, "Hi guys, to kick off the second half of the "Blown Away" tour, I've joined Instagram!"

The most popular people showcased on Carrie account aren't actually "people." Her dogs seem to be her favorite things to Instagram!

There aren't any pics on there of her hubby yet either! Bummer!
