Apparently, Carrie Underwood’s Calia by Carrie gym bags double as great diaper bags. Fans got a peek into the star's new life as a mom when she shared a photo on Twitter of baby Isaiah’s diaper bag, which is actually an accessory from her fitness wear line.

And Underwood doesn't carry light. The bag is filled to the brim not with workout gear, but adorable baby gear. Burp cloths, a knit monkey, a changing pad, everything any new mom would have — a positive reminder that Underwood is just like the rest of the moms out there! Isaiah has got everything he needs in the practical, but chic bag.

"Our @CALIAbyCarrie totes, of course, are perfect for the gym, but they also make fantastic diaper bags! #MomLife," the singer writes.

The ‘Everyday Tote’ is just one of several cute accessories in Underwood’s line, which is available exclusively at Dick’s Sporting Goods and at line's website, caliastudio.com. Calia launched in March and is already picking up steam with cute-but-comfy tanks, leggings, yoga mats and more.

When Underwood isn’t spending time with Isaiah, she is busy helping Brad Paisley open for the Rolling Stones and performing at the Grand Ole Opry, where she will be July 24 and 25. Baby Isaiah is nearly four months old, but the singer recently revealed her recovery from his birth was somewhat complicated, as she had to have a C-section delivery and was not able to be active for weeks afterward. That didn’t keep her down for long, though, as she made her TV debut at the CMT Music Awards on June 10 and looked just as stunning as ever!

As for new music? Look for a baby-inspired song on the singer's next album, which she's hard at work on now.
