Isaiah Fisher can now confirm that the wheels on the bus do go round and round. Mama-on-the-go Carrie Underwood shared another glimpse into life with her leading men over the weekend, with a photo of husband Mike Fisher and baby Isaiah enjoying life on the tour bus. The two gaze out the bus window, watching the scenery pass by as Fisher props the little man up so he can get a better view.

Underwood has been busy since her post-baby stage debut on the CMT Music Awards back in June. Her return to the spotlight has been marked with her 21st No. 1 single, studio time to finish up a brand new album and selling out four shows at the Grand Ole Opry in one weekend. Not too shabby for the country superstar/mom extraordinaire/fitness wear entrepreneur.

Isaiah was born Feb. 27, and it seems like Underwood and Fisher — married now for five years — have adjusted just fine, if Underwood’s Instagram photos of the little family are any indication. Underwood says the couple keeps connected, ironically, by having some space every once and a while, particularly when she is working on a new project.

“He stays away. That whole creative process is such a weird thing, and I’ve talked to other people in the music business and friends and what they do and we all kind of have our own ‘isms," she once remarked.

Underwood and Fisher also make sure to keep fit together, keeping each other going when it’s tough. "The couple that slays together … stays together! Working out is always better with a partner! #StayThePath," Underwood wrote under a picture of Fisher and herself working out — him admittedly looking a little defeated.

Underwood has said new music is slated to arrive later this year.
